Use an empty string ("") if you do not want to deny the replication of credentials of any users or computers. By default, Administrators, Server Operators, Backup Operators, Account Operators, and the Denied RODC Password Replication Group are denied. By default, the Denied RODC Password Replication Group includes Cert Publishers, Domain Admins, Enterprise Admins, Enterprise Domain Controllers, Enterprise Read-Only Domain Controllers, Group Policy Creator Owners, the krbtgt account, and Schema Admins.

-InstallDns
Specifies whether the DNS Server service should be installed and configured on the domain controller. For domain controller installation, if this parameter is left unspecified and the current domain already hosts and stores the DNS names for the domain, then the default for this parameter is $true and the DNS server will be installed. Otherwise, if DNS domain names are hosted outside of Active Directory, the default is $false and no DNS server will be installed.
To test if DNS domain names are hosted outside of Active Directory, this cmdlet uses a start of authority (SOA) type DNS query to ask the question "Does a zone exist for the domain name?" For example, if the value of -DomainName is "corp.contoso.com", Active Directory performs an SOA query for "corp.contoso.com" and ensures that the zone name in the response is " corp.contoso.com".

-MoveInfrastructureOperationMasterRoleIfNecessary
Use this parameter to transfer the infrastructure master role to the domain controller being installed. To successfully complete the transfer, the -NoGlobalCatalog switch parameter must be included as well. Do not specify this parameter if you want the infrastructure master role to remain where it currently is.

-NoDnsOnNetwork
Specifies that DNS service is not available on the network. This parameter is used only when the IP setting of the network adapter for this computer is not configured with the name of a DNS server for name resolution. It indicates that a DNS server will be installed on this computer for name resolution. Otherwise, the IP settings of the network adapter must first be configured with the address of a DNS server.
Omitting this parameter (the default) indicates that the TCP/IP client settings of the network adapter on this server computer will be used to contact a DNS server. Therefore, if you are not specifying this parameter, ensure that TCP/IP client settings are first configured with a preferred DNS server address.

-NoRebootOnCompletion
If specified, the computer will not restart upon the completion of the operation to install the domain controller. By default, if this parameter is omitted the computer will restart upon the completion of the install operation. As a general rule, Microsoft support recommends that you not use this parameter except for testing or troubleshooting purposes because once configuration has completed the server will not function correctly as either a member server or a DC until it is rebooted.

-SafeModeAdministratorPassword<SecureString>
Supplies the password for the administrator account when the computer is started in Safe Mode or a variant of Safe Mode, such as Directory Services Restore Mode. If no value is specified for this parameter, the cmdlet prompts you to enter and confirm a masked password. If specified with a value, the value must be a secure string.
Supplies the password for the administrator account when the computer is started in Safe Mode or a variant of Safe Mode, such as Directory Services Restore Mode. You must supply a password that meets the password complexity rules of the domain and the password cannot be blank. If specified with a value, the value must be a secure string.
If this parameter is not specified, the cmdlet prompts you to enter and confirm a masked password. This is the preferred usage when running the cmdlet interactively. If additionally there are no other arguments specified with the cmdlet, you will be prompted to enter a masked password for this parameter but no confirmation of the password entered will be made (which is not recommended as it could allow a mistyped password to be configured). Another available advanced option is to use the ConvertTo-SecureString cmdlet and specify the password string inline as unmasked console input, which is also not a recommended security best practice in production deployments.

-SiteName<String>
Specifies the name of an existing site where you can place the new domain controller. The default value depends on the type of installation. For a new forest, the default is Default-First-Site-Name. For all other installations, the default is the site that is associated with the subnet that includes the IP address of this server. If no such site exists, the default is the site of the replication source domain controller.

-SkipPreChecks
Specifies that only a base set of validations will be performed. This behavior is equivalent to the validations that were performed when using Dcpromo.exe in earlier versions of Windows Server to add a new domain controller. When this switch parameter is set, it specifies that additional preliminary checks should be bypassed. For more information on the scope of these additional preliminary checks that the ADDSDeployment module performs by default when using Windows Server 2012, refer to the table in the section “Prerequisite Checking” in the Understand and Troubleshoot AD DS Simplified Administration in Windows Server 2012 guide (https://go.microsoft.com/fwlink/?LinkID=237244).

<CommonParameters>
This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see about_CommonParameters (https://go.microsoft.com/fwlink/p/?LinkID=113216).
Inputs
The input type is the type of the objects that you can pipe to the cmdlet.
Outputs
The output type is the type of the objects that the cmdlet emits.
Notes
By default, this cmdlet always prompts for confirmation. To bypass confirmation, you need to include the -Confirm parameter and specify a value of $false. For example,
-Confirm:$false.By default, this cmdlet is always run when executed. To see what will happen if the cmdlet runs without executing or committing installation changes, first run the cmdlet using the -WhatIf parameter to show what would happen.
