I've had a problem with NTP / w32time for months now on 1 client (out of 500+, so I know the server and network is OK).
This PC sometimes looses it's time setting all together (i.e moves to 1/1/93 or something), but mostly just outright has difficulty with NTP. I notice the communication problems in the Windows Event Logs. Example for today: over 300 of the error below in the Event/System logs.
Time Provider NtpClient: The response received from domain controller DC.domain.int is
missing the signature. The response may have been tampered with and will be ignored.
In the past, I've tried a variety of things including virus scanning, hardware diagnostics (HDD, RAM, etc). I'm sure I ran CHKDSK and SFC, but can't really remember exactly everything which was run. I know the problem never really went away. The user has just ignored it.
Anyone more familiar with Windows XP w32tm and NTP to maybe give me some pointers for this one client?
Thanks for your time!
