Thanks..More detail needed before you get a response.
You have a domain SERVER?
Did you just recently change something?
REMOVE from domain and rejoin: Success.What..I have to remove all desktops from the domain or Un-Install windwos server 2008 & what about domain group POLICY? I have to implement one policy like (only few users are allowed to access Facebook websites)Okay, ridhwan, it's obvious that you have NO experience with what you're doing. While we are HAPPY to help you when you're stumped, we don't want to explain everything you need to know about being a sys admin. Get a few of the MCTS books from MICROSOFT and do some reading. You'll learn a whole lot more that way than you could ever learn from a forum geared more towards general users than admins.

Check out the Microsoft Learning web site and learn as much as you can from there. You'll learn a lot more and a lot faster if you do.

Also, before you can do anything to fix the domain logon problems with the workstations, you will need to have domain admin privileges, and based on your other post, you don't have that. You're pretty much screwed until you have that.i do have domain admin privleges..please let me know ASAPAs Geek-4pm said, we need more details before we can give you a good answer.... If we can't get more details, you can follow my first bit of advice, as it is about as descriptive as your problem.what details u required please let me know ASAP..what is your domain architecture? what version of windows server are you using for your domain controllers? when did the problem start? what were you doing when you first noticed the problem? what have you tried already?

If there's a problem with domain authentication, you can usually just remove the affected computer from the domain and rejoin it, to fix the problem, which I suggested in my first reply. Did you try that yet?
