Time Sync

[Guest Randy]

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

Sorry, I might give incorrect information. To check the "net time" command.

Use net time /querysntp command to check the NTP server on the DC and

workstation. This link may have more details.

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.

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.

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
