The Review Options page in Server Manager also offers an optional View Script button to
create a Unicode text file that contains the current ADDSDeployment 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.
