Windows Server 2003 time is syncing with both PDC and Internet time

Hi.
We have 8 servers, all of them sync with a domain controller "DMC1".  

However, one of the servers (a Server 2003 machine) is also syncing with the Internet directly (at one of Microsoft's Time Servers), on it's own.   So every 5 minutes, it syncs with the Internet and is then off by a minute.  THEN, a minute or so later, the server syncs as it should with DMC1.

I assume I just need to "turn off" the syncing with the Internet on that one server, and all will be good.
Does anyone think that's the solution, and how do I turn off Internet time syncing?

Thanks
Rob

w32tm /query /status
this command will give you very useful information on current NTP client settings/status.

After some research, we looked at that setting you mentioned.  We saw that:
     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer

was set to 2 time servers:   "10.9.8.5,0x1 time.windows.com,0x1"
We took off the  "time.windows.com,0x1" part and it seems to be working so far.

Yes that's where I always look at when the time service is not working.

Glad to point you to the correct spot.

Ultimately, the registry key to inspect is:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Parameters\NtpServer
which will include a list of all time servers that the server is sync'ing with (listed by name or IP, each separated by a space).
For example:
    "10.9.8.5,0x1 time.windows.com,0x1"
seems to tell the server to sync with 2 time servers (which was bad, in our case, since the two were so far off each other).
