Time service goes to another DC instead of external TS

Hello,

I'm trying to set win2k sp4 server to synchronize with external time server,
for instance time.windows.com. With a third-party time utility I synchronize
successfully, so port 123 is open.

I run

C:\WINNT\Profiles\Administrator>net time /setsntp:time.windows.com
The command completed successfully.
C:\WINNT\Profiles\Administrator>net time /querysntp
The current SNTP value is: time.windows.com
The command completed successfully.

But then when I run w32tm -test -once -v, it appears that time service still
synchronizes with another domain controller.

This is happening on both PDC and BDC : PDC goes to BDC, BDC goes to PDC.
The output from w32tm follows.

I wonder, why does it not go to time.windows.com?


thanks,

IIRC, if you have an Active Directory forest, the (root) domain controller
(there is no more PDC or BDC notion with W2K) is responsible for synchronizing
the whole forest. Running net time /querysntp will reflect what you've set with
net time /setsntp. The latter command must have been run on the root domain
controller however. I think AD primes towards the settings you put manually.
Hence all domain controllers that take part in the forest do synchronize against
their parent.

See http://support.microsoft.com/kb/216734/EN-US/ for more information.
