Hi Lou,
What is the configuration of your Exchange server/s, are you running in a FE/BE setup, are you running RPC/HTTPS, are you running in a cluster?
Anyway here is a dump of all of the processes that are running on one of my test boxes, My test box is running Exchange 2003 SP2 with the latest updates. Additionally it is non clustered and not running NLB.
Hope this helps!
