time synch

I'm working on an ungoing issue. I have 3 windows 2003 servers std r2 x64bit.
2 of them are DC and 1 is a standalone.
All workstations and 1 standalone server are on a domain.
The 1 standalone server is not time synching up with the DC. Don't know what to do.
The GPO looks good but don't know how to troubleshoot.
Is there a way to list all the computers that are synching and the ones that are not?
How to fix this problem?
Thanks

When you say the server is standalone, do you mean it is not a member server of the domain?  If it is not a member of the domain, there is no reason for it to sync with the domain controllers.

Here is an article how Windows Time Service works
http://technet.microsoft.com/en-us/library/cc773013%28v=ws.10%29.aspx

This article provides details for setting up time sync for your domain.  It includes the W32tm command which you should use.

Is the stand alone member server a virtual machine?  If so, then it could be picking up the time from the host server.

Try and run w32tm /resync     on the member server.

Review the Windows Time Service Tools and Settings link:

You can check the time settings manually on your standalone server.

Windows 2k3
net time /querysntp

Windows 2K8
w32 /query /source

It should show you the time server which that server will request the time from.

If it's not showing correctly then doublecheck your GPO settings.

Look under the section "Windows Time Service Group Policy Settings"

Tools for troubleshooting time configuration/syncing.
You can use w32tm to configure and check time settings.

Alternatively, you can set it manually using w32tm
w32tm /config /syncfromflags:domhier /update
then run
w32tm /resync /rediscover

P.S. restarting the Time Service should also resync your server time with the configured time server.
