In the process of managing your NPS server deployment, you might find it useful to move an NPS server to another domain, to replace an NPS server, or to retire an NPS server. When you move or decommission an NPS server, unregister the NPS server in the Active Directory domains where the NPS server has permission to read the properties of user accounts in Active Directory.
To complete this procedure, you must be a member of the Administrators group.
On the domain controller, click Start, click Administrative Tools, and then click Active Directory Users and Computers. The Active Directory Users and Computers console opens.
Click Users, and then double-click RAS and IAS servers.
Click the Members tab, and then select the NPS server that you want to unregister.
Click Remove, click Yes, and then click OK.
