Mark,
I experienced the same thing. I added an enabler for VSS on my Networker 
server and scheduled backups that had been working for years, caused my 
Exchange IS to crash. I did not specify any VSS savesets, or even ALL 
savesets, just a C:\ saveset. Since it causes me grief when my production 
Exchange IS crashes, I removed the VSS enabler and no longer had the 
problem. It didn't look like anyone else has replied to this post. Did you 
ever get any information about this from anywhere else?
