IISAdministration Overview

With Windows 10 and Windows Server 2016, the IIS Team is releasing a new and simplified IISAdministration module side by side with the existing WebAdministration Cmdlets. There are many reasons behind the decision to release an entirely new PowerShell Cmdlet module and here are a few of them:

  • IISAdministration will scale better in scripts that take a long time to run with WebAdministration.
  • You can now get a direct reference to an instance of Microsoft.Web.Administration.ServerManager object and do anything that you can do in Microsoft.Web.Administration namespace alongside your scripts.
  • PowerShell pipeline compatibility was the driving force behind the design of many cmdlets. As such, IISAdministration works much better with PowerShell Pipeline.

The version of the Cmdlets which was released for Windows 10 was a rough version with room for improvement; the targeted release was Windows Server 2016 for the finished and polished product. The reason for the earlier release was to get feedback from real PowerShell users and IIS Administrators in the industry, to answer any questions, and to receive suggestions about not only the existing functionality but also potentially for new functionality our users would want from IIS Administration as it pertains to PowerShell.

Here are some examples on the usage of the new provider:


PS:>Get-IISConfigSection -SectionPath "system.webServer/defaultDocument" | Get-IISConfigCollection -CollectionName "files" | New-IISConfigCollectionElement -ConfigAttribute @{"Value" = "MyDefDoc.htm"}

Get-IISConfigSection is at the beginning of most pipelines and in the specific example above, we are first getting the "system.webServer/defaultDocument" section (Case Sensitive!), then get the files collection, and finally get a collection element with the given attribute value.

PS:>$ConfigSection = Get-IISConfigSection -SectionPath "system.applicationHost/sites"

PS:>Get-IISConfigCollection $configSection | Get-IISConfigCollectionElement -ConfigAttribute @{"Name"="Default Web Site"} | Get-IISConfigAttributeValue -AttributeName "State"

This one is more of a hybrid example where the section is first put into a variable, then used in the pipeline.

Simple Commands

The number of simple commands are greatly reduced to a few. The examples include Get-IISSite and Get-IISAppPool. Other simple operations for which the commands do not exist can be performed through pipeline operations.

PS:> Get-IISAppPool

Name            Status   CLR Ver  Pipeline Mode  Start Mode
----            ------   -------  -------------  ----------
DefaultAppPool  Started  v4.0     Integrated     OnDemand


PS:>$sm = Get-IISServerManager


As you can see, once you have access to the server manager, the sky is the limit.

Start-IISCommitDelay / Stop-IISCommitDelay

By enclosing your operations between these commands, you can make sure that your changes are committed at the same time.

These are only a handful of examples of what you can do with the new provider. Visit Online document for the complete documentation and more examples.
