I am having some issues on a Windows 2000 DC that I administer. When I try to access AD Users, I get :
Naming information can not be located because:
Logon attempt failed.
Contact your system administrator to verify that your domain is properly configured and is currently online.
I then tried to access the PC through Terminal Services, but I get the "Unable to log you on, check username and password" error message.
I then tried using a backup Admin account to log into TS, but I got "Unable to log on interactively". I then followed the steps in : http://support.microsoft.com/?id=329887
, and the error message changed to "You do not have access to logon to this Session".
I tried doing NTrights on a remote PC in case DenyInteractiveLogon was set to Everyone(even though no-one would have done this), but it didnt work.
I am very hesitant to reboot the server and it is starting to become a real concern. I would be very grateful for any answers or help anyone might be able to provide.
My next step would be to try to do a full backup and run the steps in : http://support.microsoft.com/?id=267553
, but I would like to hear from someone who had this problem and fixed it before doing this. If I have to rebuild this server it will take me over 15 hours of time.
Thank you for your help.
