So i ran into a troubling issue today. I have a single standard edition of Exchange 2010 sp2. The transport service suddenly stopped and restarted this morning. The problem is it never made it from starting to started and I couldn't restart the service. Also at the same time the CPU utilization was maxed out by the msftefd.exe process. I did some research and realize the process was related to the indexing service. I decided to temporarily disable the indexing service on my databases to try to figure out why the transport service wouldn't start. After doing so the processors returned to their normal utilization. Now I did some further research on the transport service issue. I tried this and for the life of me am not sure what i was thinking. http://technet.microsoft.com/en-us/library/bb125177
After doing so I cannot start the hub transport service. It immediately popsup an error and I see Event id 7000 and 7009 in the event logs. I have opened a case with Microsoft support and am awaiting a call back. Any suggestions in the meantime?
