The Review Options page in Server Manager also offers an optional View Script button to create a Unicode text file that contains the current ADDS Deployment configuration as a single Windows PowerShell script. This enables you to use the Server Manager graphical interface as a Windows PowerShell deployment studio. Use the Active Directory Domain Services Configuration Wizard to configure options, export the configuration, and then cancel the wizard. This process creates a valid and syntactically correct sample for further modification or direct use.
