Hello

Sorry for the late reply, I had limited network access / time in the last couple of weeks. What I could find with Google: Configuring the Windows Time service to use an external time source - directly from the horses mouth (not that I'm comparing MS to a horse or anything like that ;-)).

At point 3 it gives the instructions on how to set the polling interval and it seems to suggest that the default one is 15 minutes (900 seconds). You can edit the registry from the command line using the REG command, so implicitly you can change this value from the command line. You might need to restart some services (w32time probably) before the change takes effect.

Hope this helps. I would also recommend that you ask this question on serverfault or superuser.

PS. SEO is ok as long as useful content is provided.

Thanks, that was a lot simpler than this wild Microsoft regedit article that came up first in the Skynet results: http://support.microsoft.com/kb/314054. After reading this I just found out that you can also set up a round-robin as recommended by pool.ntp.org, like this:
net time /setsntp:"3.es.pool.ntp.org 0.europe.pool.ntp.org 2.europe.pool.ntp.org" (those are the settings for Spain).

Do you know how often XP syncronises with the NTP servers by default? Can this be changed via command line?

PS: I couldn't resist using the opportunity to make a little pun-based SEO for a friend of mine.
