To remove a server from the set of servers used as sources when importing user profiles from Microsoft Active Directory directory service, you must delete the Active Directory server from the list of Active Directory connections.
Deleting a server from this list of connections does not delete any of the content on that server. It just removes the connection to the server. User profiles found only on that Active Directory server are not imported.
Note For more information about the Manage Connections page, see Managing Active Directory Connections.
