asa.:)Please Help!!!!|||By default, the messenger service is disabled on Windows XP and Server 2003 as a securiy precaution. In most cases, this is a good thing. Unless you clearly understand the implications, do NOT start the Messenger service.

My advice is to disable Windows messaging for any SQL Agent Operators that have Windows messaging enabled.
