question on internet time sync for AD server

[Kremlar]

I have an AD server that I'd like to sync with an internet source to keep accurate time.

I've followed the steps in this article:
http://support.microsoft.com/kb/816042

However, I've found that it does not poll the NTP server automatically. I'm able to force it to sync by running:

w32tm /resync

When I run that command the time seems to sync up as it should.

Is this correct? I'm probably misunderstanding, but I thought by setting the poll interval in the registry per the instructions I was telling it how often to poll.

Do I need to setup a scheduled task to run the w32tm command, or am I overlooking a better solution?

Thanks in advance!

It does work as you suspect it should. A few caveats - it will only sync within a few minutes (less than an hour for sure by default if I recall), and for an active directory server the command is different than you list. The one you show should be more like that on a workstation to connect to it's AD for ntp.

w32tm /config /manualpeerlist:”uk.pool.ntp.org,0×8 europe.pool.ntp.org,0×8″ /syncfromflags:MANUAL /reliable:yes /update

(sub your local pools)

Also see the site I googled up for these, and note I'm probably wrong:

Thanks so much for that link... for some reason the over-complicated Microsoft article just would not work for me.

The instructions in the link you posted worked perfectly.
