Sounds again like you need a working host check for the VPN perhaps? Is
the w2k host a child of the VPN?

Look at the service/host check logic carefully. If you have a service,
there must be a host check behind it. Conversely, (IIRC) if you have a
host check, it will always be in an assumed up state until a service
check goes down, triggering the host check.

Long and short of it is, each host needs both a host check and one or
more service checks, otherwise you will find you have hosts that do not
come back up even after the service check has been fixed.
