Eugen, Thanks for your suggestions. I would try a different version of NTP, but this one has been working 100% correctly until 14:20 On Dec 02, and continues to work on the other systems. You can see this from the weekly and monthly plots. I used to have poor stability on this system until upgrading to Windows XP SP2, and others have seen a similar behaviour. It is as if something undid whatever change SP2 made. It's possible that I did upgrade some software - many programs offer to do that for you on the fly - but I would have thought the system restore would have fixed that. I also tried uninstalling QuickTime, as there is a suggestion that if the multi-media timer is enabled in Windows, that can cause these problems. As yet, I haven't found out how to determine whether the multi-media timer is enabled, and if so, how to disable it. The CPU load on the system hasn't changed either - it is well under 100% averaging, perhaps 15-20%.
