Deploy Nano Server

Applies to: Windows Server 2016


On October 9, 2018, support for the Nano Server installation option ended. Starting in Windows Server, version 1709, Nano Server is available only as a container base OS image. Check out Changes to Nano Server to learn what this means.

This topic covers information you need to deploy Nano Server images that are more customized to your needs compared to the simple examples in the Nano Server Quick Start topic. You'll find information about making a custom Nano Server image with exactly the features you want, installing Nano Server images from VHD or WIM, editing files, working with domains, dealing with packages by several methods, and working with server roles.

Nano Server Image Builder

The Nano Server Image Builder is a tool that helps you create a custom Nano Server image and bootable USB media with the aid of a graphical interface. Based on the inputs you provide, it generates reusable PowerShell scripts that allow you easily automate consistent installations of Nano Server running either Windows Server 2016 Datacenter or Standard editions.

Obtain the tool from the Download Center.

The tool also requires Windows Assessment and Deployment Kit (ADK).

Nano Server Image Builder creates customized Nano Server images in VHD, VHDX, or ISO formats and can create bootable USB media to deploy Nano server or detect the hardware configuration of a server. It also can do the following:

  • Accept the license terms
  • Create VHD, VHDX or ISO formats
  • Add server roles
  • Add device drivers
  • Set machine name, administrator password, logfile path, and timezone
  • Join a domain by using an existing Active Directory account or a harvested domain-join blob
  • Enable WinRM for communication outside the local subnet
  • Enable Virtual LAN IDs and configure static IP addresses
  • Inject new servicing packages on the fly
  • Add a setupcomplete.cmd or other customer scripts to run after the unattend.xml is processed
  • Enable Emergency Management Services (EMS) for serial port console access
  • Enable development services to enable test signed drivers and unsigned applications, PowerShell default shell
  • Enable debugging over serial, USB, TCP/IP, or IEEE 1394 protocols
  • Create USB media using WinPE that will partition the server and install the Nano image
  • Create USB media using WinPE that will detect your existing Nano Server hardware configuration and report all the details in a log and on-screen. This includes network adapters, MAC addresses, and firmware Type (BIOS or UEFI). The detection process will also list all of the volumes on the system and the devices that do not have a driver included in the Server Core drivers package.

If any of these are unfamiliar to you, review the remainder of this topic and the other Nano Server topics so that you'll be prepared to provide the tool with the information it will need.

Creating a custom Nano Server image

For Windows Server 2016, Nano Server is distributed on the physical media, where you will find a NanoServer folder; this contains a .wim image and a sub-folder called Packages. It is these package files that you use to add server roles and features to the VHD image, which you then boot to.

You can also find and install these packages with the NanoServerPackage provider of PackageManagement (OneGet) PowerShell module. See the Installing roles and features online section of this topic.

This table shows the roles and features that are available in this release of Nano Server, along with the Windows PowerShell options that will install the packages for them. Some packages are installed directly with their own Windows PowerShell switches (such as -Compute); others you install by passing package names to the -Package parameter, which you can combine in a comma-separated list. You can dynamically list available packages using the Get-NanoServerPackage cmdlet.

Role or feature Option
Hyper-V role (including NetQoS) -Compute
Failover Clustering and other components, detailed after this table -Clustering
Basic drivers for a variety of network adapters and storage controllers. This is the same set of drivers included in a Server Core installation of Windows Server 2016. -OEMDrivers
File Server role and other storage components, detailed after this table -Storage

Note: See IIS on Nano Server for details about working with IIS.

Host support for Windows Containers -Containers
System Center Virtual Machine Manager agent -Package Microsoft-NanoServer-SCVMM-Package

-Package Microsoft-NanoServer-SCVMM-Compute-Package

Note: Use the SCVMM Compute package only if you are monitoring Hyper-V. For hyper-converged deployments in VMM, you should also specify the -Storage parameter. For more details, see the VMM documentation.

System Center Operations Manager agent Installed separately. See the System Center Operations Manager documentation for more details at Install Agent on Nano Server

Note: This package is only available for the Datacenter edition of Nano Server.

Simple Network Management Protocol (SNMP) agent -Package

Note: Not included with Windows Server 2016 installation media. Available online only. See Installing roles and features online for details.

IPHelper service which provides tunnel connectivity using IPv6 transition technologies (6to4, ISATAP, Port Proxy, and Teredo), and IP-HTTPS -Package

Note: Not included with Windows Server 2016 installation media. Available online only. See Installing roles and features online for details.


When you install packages with these options, a corresponding language pack is also installed based on selected server media locale. You can find the available language packs and their locale abbreviations in the installation media in sub-folders named for the locale of the image.


When you use the -Storage parameter to install File Services, File Services is not actually enabled. Enable this feature from a remote computer with Server Manager.

Failover Clustering items installed by the -Clustering parameter

  • Failover Clustering role
  • VM Failover Clustering
  • Storage Spaces Direct (S2D)
  • Storage Quality of Service
  • Volume Replication Clustering
  • SMB Witness Service

File and storage items installed by the -Storage parameter

  • File Server role
  • Data Deduplication
  • Multipath I/O, including a driver for Microsoft Device-Specific Module (MSDSM)
  • ReFS (v1 and v2)
  • iSCSI Initiator (but not iSCSI Target)
  • Storage Replica
  • Storage Management Service with SMI-S support
  • SMB Witness Service
  • Dynamic Volumes
  • Basic Windows storage providers (for Windows Storage Management)

Installing a Nano Server VHD

This example creates a GPT-based VHDX image with a given computer name and including Hyper-V guest drivers, starting with Nano Server installation media on a network share. In an elevated Windows PowerShell prompt, start with this cmdlet:

Import-Module <Server media location>\NanoServer\NanoServerImageGenerator; New-NanoServerImage -DeploymentType Guest -Edition Standard -MediaPath \\Path\To\Media\server_en-us -BasePath .\Base -TargetPath .\FirstStepsNano.vhdx -ComputerName FirstStepsNano

The cmdlet will accomplish all of these tasks:

  1. Select Standard as a base edition

  2. Prompt you for the Administrator password

  3. Copy installation media from \\Path\To\Media\server_en-us into .\Base

  4. Convert the WIM image to a VHD. (The file extension of the target path argument determines whether it creates an MBR-based VHD for Generation 1 virtual machines versus a GPT-based VHDX for Generation 2 virtual machines.)

  5. Copy the resulting VHD into .\FirstStepsNano.vhdx

  6. Set the Administrator password for the image as specified

  7. Set the computer name of the image to FirstStepsNano

  8. Install the Hyper-V guest drivers

All of this results in an image of .\FirstStepsNano.vhdx.

The cmdlet generates a log as it runs and will let you know where this log is located once it is finished. The WIM-to-VHD conversion accomplished by the companion script generates its own log in %TEMP%\Convert-WindowsImage\<GUID> (where <GUID> is a unique identifier per conversion session).

As long as you use the same base path, you can omit the media path parameter every time you run this cmdlet, since it will use cached files from the base path. If you don't specify a base path, the cmdlet will generate a default one in the TEMP folder. If you want to use different source media, but the same base path, you should specify the media path parameter, however.


You now have the option to specify the Nano Server edition to build either the Standard or Datacenter edition. Use the -Edition parameter to specify Standard or Datacenter editions.

Once you have an existing image, you can modify it as needed using the Edit-NanoServerImage cmdlet.

If you do not specify a computer name, a random name will be generated.

Installing a Nano Server WIM

  1. Copy the NanoServerImageGenerator folder from the \NanoServer folder in the Windows Server 2016 ISO a local folder on your computer.

  2. Start Windows PowerShell as an administrator, change directory to the folder where you placed the NanoServerImageGenerator folder and then import the module with Import-Module .\NanoServerImageGenerator -Verbose.


    You might have to adjust the Windows PowerShell execution policy. Set-ExecutionPolicy RemoteSigned should work well.

To create a Nano Server image to serve as a Hyper-V host, run the following:

New-NanoServerImage -Edition Standard -DeploymentType Host -MediaPath <path to root of media> -BasePath .\Base -TargetPath .\NanoServerPhysical\NanoServer.wim -ComputerName <computer name> -OEMDrivers -Compute -Clustering`


  • MediaPath is the root of the DVD media or ISO image containing Windows Server 2016 .
  • -BasePath will contain a copy of the Nano Server binaries, so you can use New-NanoServerImage -BasePath without having to specify -MediaPath in future runs.
  • -TargetPath will contain the resulting .wim file containing the roles & features you selected. Make sure to specify the .wim extension.
  • -Compute adds the Hyper-V role.
  • -OemDrivers adds a number of common drivers.

You will be prompted to enter an administrator password.

For more information, run Get-Help New-NanoServerImage -Full.

Boot into WinPE and ensure that the .wim file just created is accessible from WinPE. (You could, for example, copy the .wim file to a bootable WinPE image on a USB flash drive.)

Once WinPE boots, use Diskpart.exe to prepare the target computer's hard drive. Run the following Diskpart commands (modify accordingly, if you're not using UEFI & GPT):


These commands will delete all data on the hard drive:

Select disk 0
Convert GPT
Create partition efi size=100
Format quick FS=FAT32 label=System
Assign letter=s
Create partition msr size=128
Create partition primary
Format quick FS=NTFS label=NanoServer
Assign letter=n
List volume

Apply the Nano Server image (adjust the path of the .wim file):

Dism.exe /apply-image /imagefile:.\NanoServer.wim /index:1 /applydir:n:\
Bcdboot.exe n:\Windows /s s:

Remove the DVD media or USB drive and reboot your system with Wpeutil.exe Reboot

Editing files on Nano Server locally and remotely

In either case, connect to Nano Server, such as with Windows PowerShell remoting.

Once you've connected to Nano Server, you can edit a file residing on your local computer by passing the file's relative or absolute path to the psEdit command, for example: psEdit C:\Windows\Logs\DISM\dism.log or psEdit .\myScript.ps1

Edit a file residing on the remote Nano Server by starting a remote session with Enter-PSSession -ComputerName -Credential ~\Administrator and then passing the file's relative or absolute path to the psEdit command like this: psEdit C:\Windows\Logs\DISM\dism.log

Installing roles and features online


If you install an optional Nano Server package from media or online repository, it won't have recent security fixes included. To avoid a version mismatch between the optional packages and base operating system, you should install the latest cumulative update immediately after installing any optional packages and before restarting the server.

Installing roles and features from a package repository

You can find and install Nano Server packages from the online package repository by using the NanoServerPackage provider of the PackageManagement PowerShell module. To install this provider, use these cmdlets:

Install-PackageProvider NanoServerPackage
Import-PackageProvider NanoServerPackage


If you experience errors when running Install-PackageProvider, check that you have installed the latest cumulative update (KB3206632 or later), or use Save-Module as follows:

Save-Module -Path $Env:ProgramFiles\WindowsPowerShell\Modules\ -Name NanoServerPackage -MinimumVersion
Import-PackageProvider NanoServerPackage

Once this provider is installed and imported, you can search for, download, and install Nano Server packages using cmdlets designed specifically for working with Nano Server packages:


You can also use the generic PackageManagement cmdlets and specify the NanoServerPackage provider:

Find-Package -ProviderName NanoServerPackage
Save-Package -ProviderName NanoServerPackage
Install-Package -ProviderName NanoServerPackage
Get-Package -ProviderName NanoServerPackage

To use any of these cmdlets with Nano Server packages on Nano Server, add -ProviderName NanoServerPackage. If you don't add the -ProviderName parameter, PackageManagement will iterate all of the providers. For more details on these cmdlets, run Get-Help <cmdlet>. Here are some common usage examples:

Searching for Nano Server packages

You can use either Find-NanoServerPackage or Find-Package -ProviderName NanoServerPackage to search for and return a list of Nano Server packages that are available in the online repository. For example, you can get a list of all the latest packages:


Running Find-Package -ProviderName NanoServerPackage -DisplayCulture displays all available cultures.

If you need a specific locale version, such as US English, you could use Find-NanoServerPackage -Culture en-us or Find-Package -ProviderName NanoServerPackage -Culture en-us or Find-Package -Culture en-us -DisplayCulture.

To find a specific package by package name, use the -Name parameter. This parameter also accepts wildcards. For example, to find all packages with VMM in the name, use Find-NanoServerPackage -Name *VMM* or Find-Package -ProviderName NanoServerPackage -Name *VMM*.

You can find a particular version with the -RequiredVersion, -MinimumVersion, or -MaximumVersion parameters. To find all available versions, use -AllVersions. Otherwise, only the latest version is returned. For example: Find-NanoServerPackage -Name *VMM* -RequiredVersion 10.0.14393.0. Or, for all versions: Find-Package -ProviderName NanoServerPackage -Name *VMM* -AllVersions

Installing Nano Server packages

You can install a Nano Server package (including its dependency packages, if any) to Nano Server either locally or an offline image with either Install-NanoServerPackage or Install-Package -ProviderName NanoServerPackage. Both of these accept input from the pipeline.

To install the latest version of a Nano Server package to an online Nano Server, use either Install-NanoServerPackage -Name Microsoft-NanoServer-Containers-Package or Install-Package -Name Microsoft-NanoServer-Containers-Package. PackageManagement will use the culture of the Nano Server.

You can install a Nano Server package to an offline image while specifying a particular version and culture, like this:

Install-NanoServerPackage -Name Microsoft-NanoServer-DCB-Package -Culture de-de -RequiredVersion 10.0.14393.0 -ToVhd C:\MyNanoVhd.vhd


Install-Package -Name Microsoft-NanoServer-DCB-Package -Culture de-de -RequiredVersion 10.0.14393.0 -ToVhd C:\MyNanoVhd.vhd

Here are some examples of pipelining package search results to the installation cmdlet:

Find-NanoServerPackage *dcb* | Install-NanoServerPackage finds any packages with dcb in the name and then installs them.

Find-Package *nanoserver-compute-* | Install-Package finds packages with nanoserver-compute- in the name and installs them.

Find-NanoServerPackage -Name *nanoserver-compute* | Install-NanoServerPackage -ToVhd C:\MyNanoVhd.vhd finds packages with compute in the name and installs them to an offline image.

Find-Package -ProviderName NanoserverPackage *nanoserver-compute-* | Install-Package -ToVhd C:\MyNanoVhd.vhd does the same thing with any package that has nanoserver-compute- in the name.

Downloading Nano Server packages

Save-NanoServerPackage or Save-Package allow you to download packages and save them without installing them. Both cmdlets accept input from the pipeline.

For example, to download and save a Nano Server package to a directory that matches the wildcard path, use Save-NanoServerPackage -Name Microsoft-NanoServer-DNS-Package -Path C:\ In this example, -Culture wasn't specified, so the culture of the local machine will be used. No version was specified, so the latest version will be saved.

Save-Package -ProviderName NanoServerPackage -Name Microsoft-NanoServer-IIS-Package -Path C:\ -Culture it-IT -MinimumVersion 10.0.14393.0 saves a particular version and for the Italian language and locale.

You can send search results through the pipeline as in these examples:

Find-NanoServerPackage -Name *containers* -MaximumVersion 10.2 -MinimumVersion 1.0 -Culture es-ES | Save-NanoServerPackage -Path C:\


Find-Package -ProviderName NanoServerPackage -Name *shield* -Culture es-ES | Save-Package -Path

Inventory installed packages

You can discover which Nano Server packages are installed with Get-Package. For example, see which packages are on Nano Server with Get-Package -ProviderName NanoserverPackage.

To check the Nano Server packages that are installed in an offline image, run Get-Package -ProviderName NanoserverPackage -FromVhd C:\MyNanoVhd.vhd.

Installing roles and features from local source

Though offline installation of server roles and other packages is recommended, you might need to install them online (with the Nano Server running) in container scenarios. To do this, follow these steps:

  1. Copy the Packages folder from the installation media locally to the running Nano Server (for example, to C:\packages).

  2. Create a new Unattend.xml file on another computer and then copy it to Nano Server. You can copy and paste this XML content into the XML file you created (this example shows installing the IIS package):

<?xml version=1.0 encoding=utf-8?>
    <unattend xmlns=urn:schemas-microsoft-com:unattend>
        <package action=install>
            <assemblyIdentity name=Microsoft-NanoServer-IIS-Feature-Package version=10.0.14393.0 processorArchitecture=amd64 publicKeyToken=31bf3856ad364e35 language=neutral />
            <source location=c:\packages\ />
        <package action=install>
            <assemblyIdentity name=Microsoft-NanoServer-IIS-Feature-Package version=10.0.14393.0 processorArchitecture=amd64 publicKeyToken=31bf3856ad364e35 language=en-US />
            <source location=c:\packages\en-us\ />
    <cpi:offlineImage cpi:source= xmlns:cpi=urn:schemas-microsoft-com:cpi />
  1. In the new XML file you created (or copied), edit C:\packages to the directory you copied the content of Packages to.

  2. Switch to the directory with the newly created XML file and run: dism /online /apply-unattend:.\unattend.xml

  3. Confirm that the package and its associated language pack is installed correctly by running: dism /online /get-packages

    You should see Package Identity : Microsoft-NanoServer-IIS-Package~31bf3856ad364e35~amd64~en-US~10.0.10586.0 listed twice, once for Release Type : Language Pack and once for Release Type : Feature Pack.

Customizing an existing Nano Server VHD

You can change the details of an existing VHD by using the Edit-NanoServerImage cmdlet, as in this example: Edit-NanoServerImage -BasePath .\Base -TargetPath .\BYOVHD.vhd

This cmdlet does the same things as New-NanoServerImage, but changes the existing image instead of converting a WIM to a VHD. It supports the same parameters as New-NanoServerImage with the exception of -MediaPath and -MaxSize, so the initial VHD must have been created with those parameters before you can make changes with Edit-NanoServerImage.

Additional tasks you can accomplish with New-NanoServerImage and Edit-NanoServerImage

Joining domains

New-NanoServerImage offers two methods of joining a domain; both rely on offline domain provisioning, but one harvests a blob to accomplish the join. In this example, the cmdlet harvests a domain blob for the Contoso domain from the local computer (which of course must be part of the Contoso domain), then it performs offline provisioning of the image using the blob:

New-NanoServerImage -Edition Standard -DeploymentType Host -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\JoinDomHarvest.vhdx -ComputerName JoinDomHarvest -DomainName Contoso

When this cmdlet completes, you should find a computer named JoinDomHarvest in the Active Directory computer list.

You can also use this cmdlet on a computer that is not joined to a domain. To do this, harvest a blob from any computer that is joined to the domain, and then provide the blob to the cmdlet yourself. Note that when you harvest such a blob from another computer, the blob already includes that computer's name--so if you try to add the -ComputerName parameter, an error will result.

You can harvest the blob with this command:

/Domain Contoso
/Machine JoiningDomainsNoHarvest
/SaveFile JoiningDomainsNoHarvest.djoin

Run New-NanoServerImage using the harvested blob:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\JoinDomNoHrvest.vhd -DomainBlobPath .\Path\To\Domain\Blob\JoinDomNoHrvestContoso.djoin

In the event that you already have a node in the domain with the same computer name as your future Nano Server, you could reuse the computer name by adding the -ReuseDomainNode parameter.

Adding additional drivers

Nano Server offers a package that includes a set of basic drivers for a variety of network adapters and storage controllers; it's possible that drivers for your network adapters might not be included. You can use these steps to find drivers in a working system, extract them, and then add them to the Nano Server image.

  1. Install Windows Server 2016 on the physical computer where you will run Nano Server.
  2. Open Device Manager and identify devices in the following categories:
  3. Network adapters
  4. Storage controllers
  5. Disk drives
  6. For each device in these categories, right-click the device name, and click Properties. In the dialog that opens, click the Driver tab, and then click Driver Details.
  7. Note the filename and path of the driver file that appears. For example, let's say the driver file is e1i63x64.sys, which is in C:\Windows\System32\Drivers.
  8. In a command prompt, search for the driver file and search for all instances with dir e1i*.sys /s /b. In this example, the driver file is also present in the path C:\Windows\System32\DriverStore\FileRepository\net1ic64.inf_amd64_fafa7441408bbecd\e1i63x64.sys.
  9. In an elevated command prompt, navigate to the directory where the Nano Server VHD is and run the following commands:
md mountdir
dism\dism /Mount-Image /ImageFile:.\NanoServer.vhd /Index:1 /MountDir:.\mountdir
dism\dism /Add-Driver /image:.\mountdir /driver: C:\Windows\System32\DriverStore\FileRepository\net1ic64.inf_amd64_fafa7441408bbecd
dism\dism /Unmount-Image /MountDir:.\MountDir /Commit
  1. Repeat these steps for each driver file you need.


In the folder where you keep your drivers, both the SYS files and corresponding INF files must be present. Also, Nano Server only supports signed, 64-bit drivers.

Injecting drivers

Nano Server offers a package that includes a set of basic drivers for a variety of network adapters and storage controllers; it's possible that drivers for your network adapters might not be included. You can use this syntax to have New-NanoServerImage search the directory for available drivers and inject them into the Nano Server image:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\InjectingDrivers.vhdx -DriverPath .\Extra\Drivers


In the folder where you keep your drivers, both the SYS files and corresponding INF files must be present. Also, Nano Server only supports signed, 64-bit drivers.

Using the -DriverPath parameter, you can also pass a array of paths to driver .inf files:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\InjectingDrivers.vhdx -DriverPath .\Extra\Drivers\netcard64.inf

Connecting with WinRM

To be able to connect to a Nano Server computer using Windows Remote Management (WinRM) (from another computer that is not on the same subnet), open port 5985 for inbound TCP traffic on the Nano Server image. Use this cmdlet:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\ConnectingOverWinRM.vhd -EnableRemoteManagementPort

Setting static IP addresses

To configure a Nano Server image to use static IP addresses, first find the name or index of the interface you want to modify by using Get-NetAdapter, netsh, or the Nano Server Recovery Console. Use the -Ipv6Address, -Ipv6Dns, -Ipv4Address, -Ipv4SubnetMask, -Ipv4Gateway and -Ipv4Dns parameters to specify the configuration, as in this example:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\StaticIpv4.vhd -InterfaceNameOrIndex Ethernet -Ipv4Address -Ipv4SubnetMask -Ipv4Gateway -Ipv4Dns

Custom image size

You can configure the Nano Server image to be a dynamically expanding VHD or VHDX with the -MaxSize parameter, as in this example:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\BigBoss.vhd -MaxSize 100GB

Embedding custom data

To embed your own script or binaries in the Nano Server image, use the -CopyPath parameter to pass an array of files and directories to be copied. The -CopyPath parameter can also accept a hashtable to specify the destination path for files and directories.

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\BigBoss.vhd -CopyPath .\tools

Running custom commands after the first boot

To run custom commands as part of setupcomplete.cmd, use the -SetupCompleteCommand parameter to pass an array of commands:

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\NanoServer.wim -SetupCompleteCommand @(echo foo, echo bar)

Running custom PowerShell scripts as part of image creation

To run custom PowerShell scripts as part of the image creation process, use the -OfflineScriptPath parameter to pass an array of paths to .ps1 scripts. If those scripts take arguments, use the -OfflineScriptArgument to pass a hashtable of additional arguments to the scripts.

New-NanoServerImage -DeploymentType Host -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\NanoServer.wim -OfflineScriptPath C:\MyScripts\custom.ps1 -OfflineScriptArgument @{Param1=Value1; Param2=Value2}

Support for development scenarios

If you want to develop and test on Nano Server, you can use the -Development parameter. This will enable PowerShell as the default local shell, enable installation of unsigned drivers, copy debugger binaries, open a port for debugging, enable test signing, and enable installation of AppX packages without a developer license:

New-NanoServerImage -DeploymentType Guest -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\NanoServer.wim -Development

Custom unattend file

If you want to use your own unattend file, use the -UnattendPath parameter:

New-NanoServerImage -DeploymentType Guest -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\NanoServer.wim -UnattendPath \\path\to\unattend.xml

Specifying an administrator password or computer name in this unattend file will override the values set by -AdministratorPassword and -ComputerName.


Nano Server does not support setting TCP/IP settings via unattend files. You can use Setupcomplete.cmd to configure TCP/IP settings.

Collecting log files

If you want to collect the log files during image creation, use the -LogPath parameter to specify a directory where all the log files are copied.

New-NanoServerImage -DeploymentType Guest -Edition Standard -MediaPath \\Path\To\Media\en_us -BasePath .\Base -TargetPath .\NanoServer.wim -LogPath C:\Logs


Some parameters on New-NanoServerImage and Edit-NanoServerImage are for internal use only and can be safely ignored. These include the -SetupUI and -Internal parameters.

Windows Server App installer

Windows Server App (WSA) installer provides a reliable installation option for Nano Server. Since Windows Installer (MSI) is not supported on Nano Server, WSA is also the only installation technology available for non-Microsoft products. WSA leverages Windows app package technology designed to install and service applications safely and reliably, using a declarative manifest. It extends the Windows app package installer to support Windows Server-specific extensions, with the limitation that WSA does not support installing drivers.

Creating and installing a WSA package on Nano Server involves steps for both the publisher and the consumer of the package.

The package publisher should do the following:

  1. Install Windows 10 SDK, which includes the tools needed to create a WSA package: MakeAppx, MakeCert, Pvk2Pfx, SignTool.
  2. Declare a manifest: Follow the WSA manifest extension schema to create the manifest file, AppxManifest.xml.
  3. Use the MakeAppx tool to create a WSA package.
  4. Use MakeCert and Pvk2Pfx tools to create the certificate, and then use Signtool to sign the package.

Next, the package consumer should follow these steps:

  1. Run the Import-Certificate PowerShell cmdlet to import the publisher's certificate from Step 4 above to Nano Server with the certStoreLocation at Cert:\LocalMachine\TrustedPeople. For example: Import-Certificate -FilePath .\xyz.cer -CertStoreLocation Cert:\LocalMachine\TrustedPeople
  2. Install the app on Nano Server by running the Add-AppxPackage PowerShell cmdlet to install a WSA package on Nano Server. For example: Add-AppxPackage wsaSample.appx

Additional resources for creating apps

WSA is server extension of Windows app package technology (though it is not hosted in Microsoft Store). If you want to publish apps with WSA,these topics will help you familiarize yourself with the app package pipeline:

Installing drivers on Nano Server

You can install non-Microsoft drivers on Nano Server by using INF driver packages. These include both Plug-and-Play (PnP) driver packages and File System Filter driver packages. Network Filter drivers are not currently supported on Nano Server.

Both PnP and File System Filter driver packages must follow the Universal driver requirements and installation process, as well as general driver package guidelines such as signing. They are documented at these locations:

Installing driver packages offline

Supported driver packages can be installed on Nano Server offline via DISM.exe or DISM PowerShell cmdlets.

Installing driver packages online

PnP driver packages can be installed to Nano Server online by using PnpUtil. Online driver installation for non-PnP driver packages is not currently supported on Nano Server.

Joining Nano Server to a domain

To add Nano Server to a domain online

  1. Harvest a data blob from a computer in the domain that is already running Windows Threshold Server using this command:

    djoin.exe /provision /domain <domain-name> /machine <machine-name> /savefile .\odjblob

    This saves the data blob in a file called odjblob.

  2. Copy the odjblob file to the Nano Server computer with these commands:

    net use z: \\<ip address of Nano Server>\c$


    If the net use command fails, you probably need to adjust Windows Firewall rules. To do this, first open an elevated command prompt, start Windows PowerShell and then connect to the Nano Server computer with Windows PowerShell Remoting with these commands:

    Set-Item WSMan:\localhost\Client\TrustedHosts <IP address of Nano Server>

    $ip = <ip address of Nano Server>

    Enter-PSSession -ComputerName $ip -Credential $ip\Administrator

    When prompted, provide the Administrator password, then run this command to set the firewall rule:

    netsh advfirewall firewall set rule group=File and Printer Sharing new enable=yes

    Exit Windows PowerShell with Exit-PSSession, and then retry the net use command. If successful, continue copying the odjblob file contents to the Nano Server.

    md z:\Temp

    copy odjblob z:\Temp

  3. Check the domain you want to join Nano Server to and ensure that DNS is configured. Also, verify that name resolution of the domain or a domain controller works as expected. To do this, open an elevated command prompt, start Windows PowerShell and then connect to the Nano Server computer with Windows PowerShell remoting with these commands:

    Set-Item WSMan:\localhost\Client\TrustedHosts <IP address of Nano Server>

    $ip = <ip address of Nano Server>

    Enter-PSSession -ComputerName $ip -Credential $ip\Administrator

    When prompted, provide the Administrator password. Nslookup is not available on Nano Server, so you can verify name resolution with Resolve-DNSName.

  4. If name resolution succeeds, then in the same Windows PowerShell session, run this command to join the domain:

    djoin /requestodj /loadfile c:\Temp\odjblob /windowspath c:\windows /localos

  5. Restart the Nano Server computer, and then exit the Windows PowerShell session:

    shutdown /r /t 5


  6. After you have joined Nano Server to a domain, add the domain user account to the Administrators group on the Nano Server.

  7. For security, remove the Nano Server from the trusted hosts list with this command: Set-Item WSMan:\localhost\client\TrustedHosts

Alternate method to join a domain in one step

First, harvest the data blob from another computer running Windows Threshold Server that is already in your domain using this command:

djoin.exe /provision /domain <domain-name> /machine <machine-name> /savefile .\odjblob

Open the file odjblob (perhaps in Notepad), copy its contents, and then paste the contents into the <AccountData> section of the Unattend.xml file below.

Put this Unattend.xml file into the C:\NanoServer folder, and then use the following commands to mount the VHD and apply the settings in the offlineServicing section:

dism\dism /Mount-ImagemediaFile:.\NanoServer.vhd /Index:1 /MountDir:.\mountdir
dism\dismmedia:.\mountdir /Apply-Unattend:.\unattend.xml

Create a Panther folder (used by Windows systems for storing files during setup; see Windows 7, Windows Server 2008 R2, and Windows Vista setup log file locations if you're curious), copy the Unattend.xml file to it, and then unmount the VHD with these commands:

md .\mountdir\windows\panther
copy .\unattend.xml .\mountdir\windows\panther
dism\dism /Unmount-Image /MountDir:.\mountdir /Commit

The first time you boot Nano Server from this VHD, the other settings will be applied.

After you have joined Nano Server to a domain, add the domain user account to the Administrators group on the Nano Server.

Working with server roles on Nano Server

Using Hyper-V on Nano Server

Hyper-V works the same on Nano Server as it does on Windows Server in Server Core mode, with two exceptions:

  • You must perform all management remotely and the management computer must be running the same build of Windows Server as the Nano Server. Older versions of Hyper-V Manager or Hyper-V Windows PowerShell cmdlets will not work.

  • RemoteFX is not available.

In this release, these features of Hyper-V have been verified:

  • Enabling Hyper-V

  • Creation of Generation 1 and Generation 2 virtual machines

  • Creation of virtual switches

  • Starting virtual machines and running Windows guest operating systems

  • Hyper-V Replica

If you want to perform a live migration of virtual machines, create a virtual machine on an SMB share, or connect resources on an existing SMB share to an existing virtual machine, it is vital that you configure authentication correctly. You have two options for doing this:

Constrained delegation

Constrained delegation works exactly the same as in previous releases. Refer to these articles for more information:


First, refer to the Using Windows PowerShell remoting section of this topic to enable and test CredSSP. Then, on the management computer, you can use Hyper-V Manager and select the option to connect as another user. Hyper-V Manager will use CredSSP. You should do this even if you are using your current account.

Windows PowerShell cmdlets for Hyper-V can use CimSession or Credential parameters, either of which work with CredSSP.

Using Failover Clustering on Nano Server

Failover clustering works the same on Nano Server as it does on Windows Server in Server Core mode, but keep these caveats in mind:

  • Clusters must be managed remotely with Failover Cluster Manager or Windows PowerShell.

  • All Nano Server cluster nodes must be joined to the same domain, similar to cluster nodes in Windows Server.

  • The domain account must have Administrator privileges on all Nano Server nodes, as with cluster nodes in Windows Server.

  • All commands must be run in an elevated command prompt.


Additionally, certain features are not supported in this release:

  • You cannot run failover clustering cmdlets on a local Nano Server through Windows PowerShell.
  • Clustering roles other than Hyper-V and File Server.

You'll find these Windows PowerShell cmdlets useful in managing Failover clusters:

You can create a new cluster with New-Cluster -Name <clustername> -Node <comma-separated cluster node list>

Once you've established a new cluster, you should run Set-StorageSetting -NewDiskPolicy OfflineShared on all nodes.

Add an additional node to the cluster with Add-ClusterNode -Name <comma-separated cluster node list> -Cluster <clustername>

Remove a node from the cluster with Remove-ClusterNode -Name <comma-separated cluster node list> -Cluster <clustername>

Create a Scale-Out File Server with Add-ClusterScaleoutFileServerRole -name <sofsname> -cluster <clustername>

You can find additional cmdlets for failover clustering at Microsoft.FailoverClusters.PowerShell.

Using DNS Server on Nano Server

To provide Nano Server with the DNS Server role, add the Microsoft-NanoServer-DNS-Package to the image (see the Creating a custom Nano Server image section of this topic. Once the Nano Server is running, connect to it and run this command from and elevated Windows PowerShell console to enable the feature:

Enable-WindowsOptionalFeature -Online -FeatureName DNS-Server-Full-Role
