Here's the situation. We have an NT4-based domain with a wide mix of machines on it--mostly Windows 2000, with a few Win98. We've recently bought a batch of machines with Windows XP Professional installed. These machines seem to have great difficulty in acknowledging that a user's domain password has changed or expired--they'll quite happily let the user log on, but the user is obviously unable to access domain resources because their password is no longer valid.
Does anyone know why Windows XP does this? Is it locally caching the logon information, or something?
