Willy,

I would be very interested in seeing such a sample. What are the WMI
Cluster Classes you mention? I have a similar need - to monitor and restart
if needed a service on a cluster, and have not had much luck to date finding
manged objects to allow me to perform this simple task. I could always issue
shell commands, but thats just ... klugy. :)

Your help would be MOST appreciated!
