Guest Randy Posted November 1, 2007 Posted November 1, 2007 How can I check that XP Pro members of my domain are actually syncing time to the DC (Server 2003 R2 SP1)? On another thread, someone suggested: "Do your computers synchronize the time with DC? Use this command to test it: net time /querysntp." So I tried that on a couple of machines and get results such as: The current SNTP value is: time.windows.com,0x1 The reason I'm looking is that there is a single XP machine in the office that is an hour off. A net time result for it also has some extra Time Zone info that none of the other machines have: Current time at \\mach1 is 11/1/2007 8:56 AM Local time (GMT-05:00) at \\mach1 is 11/1/2007 7:56 AM All the other XP's just return the current time portion of that. The problem machine is set to Eastern Standard Time with the daylight option checked. All XP's and the DC are current on updates

Guest Newell White Posted November 1, 2007 Posted November 1, 2007 RE: Time Sync On a Windows XP machine, look in the registry. HKLM\System\CurrentControlSet\Services\W32Time\Parameters Key 'Type' should have the value NT5DS This is the default setting, and specifies time sync with the PDC emulator. I believe that 'querysntp' returns the value of the Key 'NTPprovider'. Your PC will only use this if 'Type' = NTP Can't help with your offset, don't know when US daylight saving ends. -- Regards, Newell White "Randy" wrote: > How can I check that XP Pro members of my domain are actually syncing > time to the DC (Server 2003 R2 SP1)?

Guest Randy Posted November 1, 2007 Posted November 1, 2007 Re: Time Sync NT5DS is the type on the problem machine. The latest caveat is that the machine is switching back and forth between the correct time and 1 hour early. It has switched maybe 2 or three times today. I suspect it is daylight time related because the old date for switching was the last Sunday in Oct and the new date is the first Sunday in Nov. Hopefully, after the weekend, we can get it back to the correct time for the next few months.

Guest Robert L. \(MS-MVP\) Posted November 1, 2007 Posted November 1, 2007 Re: Time Sync What I tried to say is to check if the computer synchronize the DC time, use net time command. To troubleshoot "Local time (GMT-05:00) at \\mach1 is 11/1/2007 7:56 AM" issue, please refer to this post. Local time is 1 hour behind DC time http://www.chicagotech.net/netforums/viewtopic.php?p=3387#3387 -- Bob Lin, MS-MVP, MCSE & CNE Networking, Internet, Routing, VPN Troubleshooting on http://www.ChicagoTech.net How to Setup Windows, Network, VPN & Remote Access on http://www.HowToNetworking.com "Robert L.
