Add a Site System
Note You must have Modify permission for the Site security object class or instance to perform this procedure.
For example, to add a new Windows NT Server site system, click New Windows NT Server.
Note If you want to assign a CAP, distribution point, or logon point role to a Windows NT server in another domain, you must either create a trust relationship between the site server's domain and the remote domain, or you must create a client connection account in the remote domain and then specify the new SMS client network connection account in the SMS Administrator console.
