Windows SBServer 2003-based domain controller restarts hourly

Tech-Archive recommends: Fix windows errors by optimizing your registry

This problem happens sporadically giving a 60 minute warning only on the XP
boxes, the clients are a mixture of XP pro and 2000 pro machines.
The problem appears to be documented here
http://support.microsoft.com/kb/925652
and the solution appears to be documented here
http://support.microsoft.com/kb/255504

There are no other servers in the domain, though in the past the network has
been connected via VPN to a network containing another SBS server, this still
happens from time to time but the problem occurs when the VPN is disconnected.

I must confess that I am a little out of my depth here, but it seems to me
that I need to seize all five FSMO roles using ntdsutil.exe. If I do this and
it is not the solution, can I 'break' anything? Any help / suggestions would
be gratefully received. Thanks.
