This week, I faced the following issue at one of our Exchange 2007 installations. After running a succesfull SP2 upgrade (all marks were green in the upgrade window), we found out mailflow was not working as it should be. After some investigation, it seemed like the "Microsoft Transport Service" and "Microsoft MailSubmission Service" did not start. Even after a reboot, still no running services.
After lots and lots of investigation, re-running SP2 setup again (which again marked all flags green), we were almost desperate...
Until one of our colleagues found an article in the MS Knowledge Base, which let to the solution => There seemed to be a parameter in the config file of the transport services, which tries connecting to a live Microsoft website; if the service can't reach that website fast enough, it times out and the service won't start.
After modifying the config file as per the article, the services ran smoothly again. (issue has been fixed by Microsoft since Exchange RU8 apparently, which was not installed on the machine prior to SP2)
Here's the link to the complete Knowledge Base article:
http://support.microsoft.com/kb/944752 - Exchange Server 2007 managed code services do not start after you install an update rollup for Exchange Server 2007
Seems like it is valid for other Microsoft Exchange Services as well :)
Voila, I hope this can save some after-hours/midnight hours working for you readers...
