Your problem is not enough clear. Could you please detail more what is happening?

i have installed windows 7 , and my server is 2003 , i have joined the windows 7 PC to the domain , but after joining when i restart the PC i could not start the PC as domain client, it logged off automaticaly. i can use this PC as simple user administrator.

Try to recheck Active Directory and try to recheck your domain configration and domain log files.

Please let us know if you can log on with: 1. Local administrator account. 2. Local standard user account. 3. Other domain accounts 4. The problematic domain account if it is in the local administrator group. Also I suggest you check in Event Log if you can log on with any account and try to find information from the System log.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
