System Clock Losing Time

Greetings All,

I'm encountering a strange behavior I hope someone can help resolve.

We have a Windows 2000 AD domain with 60+ servers. On 3 of the servers the

system clock loses time at a rate of 16 hours every 10 mins a user is logged

in. It seems that if no user is logged in the system time remains

up-to-date. We can tell as there are no corrections indentified in the

system log. The problem happens for console users as well as RDP users.

I'm not sure where to look. Any help would be appreciated.

Regards,

Brian
