Suddenly screen scrolling (e.g in Event Viewer, dhcp control etc.) on the
server is much slower (1/3 the previous speed).

Reboot does not fix. Task manager shows c 4% proc activity only. This is
first time I have ever noticed a slow down on this machine which was not
fixed by a reboot.

Only recent activity - installing SUS 1.1 for the first time a week ago
(have downloaded patches but not actually 'approved' and rolled them out
yet).

Any ideas? - memory is 1gb, 2 proc machine.

Thanks
