Installed SEP 11.01000 MR1 and patched with latest update 11.01006 on Test Server Win 2k3 SP2 and pushed to a few test workstations XP Pro SP2. Have not encountered any problems for 2 weeks. Waiting to do live deploy after March 21st MR2 patch release...which is suppossed to correct instability problems many other people have been having problems with.

Sorry to hear about problems others have experienced but standard rule of thumb for any experienced IT administrator is to never go live with new software until at least 6 months after its release. I can't even imagine deploying something relatively untested on an Exchange server...I'm not sure I can agree with the conclusion that SEP sucks based on these facts at this time.
