Hello,
A little bit of background: your computer uses TWO accounts when logging into a Windows Domain: the Computer account, and the User account.
The Computer account is a behind-the-scenes key with a username (the computer's NETBIOS name) and a password that is made up when the computer first joins the domain. Improper domain management can cause your computer, and the server, to become out of sync concerning this account.
Ways to repair are to go into AD and delete the computer, and then go to the computer, and remove it from the domain. Wait 15 minutes, and then re-join the computer. You have to wait because your domain may be out of sync with the rest of the domain controllers, and you have to wait for a conversation cycle before AD stabilizes.
