Winlogon consuming 100% CPU on Win2003 Terminal Services.

[Guest]

Hi,

We've a problem whereby Winlogon consumes 100% CPU for up to several minutes
on several of our Win2003 terminal servers. It is completely unpredictable
as for the vast majority of time logins work fine.

They are running Win2003 SP1 and all recent critical fixes.

Any ideas where to either start looking or to get further debugging
information.

These are live systems supporting around 40 users each.

We've ruled out spyware, viruses and the like. DNS settings seem fine.

Thanks

Jason.

Thanks for that, although the problem existed prior to installation of SP1
so it would seem that this hotfix is not applicable. I should have mentioned
that in my original message.

Thanks

Jason.
