Domain controller error

First reboot once your PC and if that does not work then:
when you login with your local admin account are you able to ping the DC? Also, check the IP settings to make sure they are correct. Are you using DHCP or are you static? If you are able to ping the DC adn IP settings are correct, is the computer name in Active directory? Also if the computer name is in active directory, is it disabled? If you check all these things and you are still having issues, drop the computer from the domain, rename it and create the new name in Active Directory and then add the computer back to the Domain. Somewhere along the line of following these steps, you should get the computer back inline. If other computers are able to connect to the domain then it is definitly an issue with this computer name or a setting on this computer.

Thanks
