Primary User cannot log on through RDC; User is Domain Admin. Name disappeared from "Allow log on through Terminal Services and now the policy is greyed out to all. User can log on locally to workstation and to Domain while sitting at, but no remote logging for particular User. Vista; Add Users or Group is greyed out on domain workstation in local security settings for "Allow log on through Terminal Services" Two Domain Admins in list for local security settings, but unaccessable to anyone, Regardless of how I sign in to this computer, with any Domain Admin, Local Admin, I am unable to add any other User to this list for RDC to this box. Grrrrrrrrrr. Help Please. Could this be as simple as unjoining the workstation from the network and rejoining so the primary User is once again recognized?

After checking the issue, it seems this can be a server related issue. As this forum focuses on Windows Vista specific issues, this inquiry would best be posted to server forum: http://forums.technet.microsoft.com/en-US/winservergen/threads/ The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the newsgroups regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

You lost me. How can you ascribe this to a server issue when it appears locally in Vista? More information would be helpful. Thanks
