Not sure I can help any more than Danny did, but the output from my own XP
machine is here:
http://www.david-taylor.myby.co.uk/mrtg/odin_ntp.html
and it seems stable even when running Windows Media Player or Real Player
(or perhaps even QuickTime). The only suggestion I can make are:
- are the clients which are drifting wildy perhaps portable PCs or systems
which have a variable clock rate? This could throw NTP.
- if you do a ntpq -p on those systems, do they appear to be in sync?
- are the systems set to use DMA for disk and CD/DVD access?
The general view is that XP can provide a good stable time.
Cheers,
David
