I encountered a problem with a Windows XP Professional system no longer being able to authenticate with the domain controller after I replaced the disk drive in the system and restored the system from a backup. Whenever the user tried logging into the domain or I tried logging in as the domain administrator, the following message appeared:
|Windows cannot connect to the
domain, either because the domain controller is down or otherwise unavailable,
or because your computer account was not found. Please try again later. If this
message continues to appear, contact your system administrator for assistance.
The problem went away on its own, but only for a couple of days, then recurred. I took the system out of the domain and put it in a workgroup, rebooted, then put it back in the domain to correct the problem. Apparently there are a variety of causes for such a problem.
