We just started having issues as of last night. Basically, all was good until I tried to add a users account to someones phone. It wasn't working and then noticed some activesync errors on the box. Per a KB article, it mentioned to add some reserved ports into the registry to resolve, and if the events continue to occur to remove the patch 951746 or 951748. Also, I can't get on the web whatsoever, but I can ping google and get a response.
In any case, I'm having issues now in that since last night around this time SMTP and IMAP will not start. Both give an error like "The service could not bind instance 1. The data is the error code.".
I checked netstat, but I don't see anything using or listening on SMTP or IMAP. I also tried to telnet to port 25, but don't get any connection.
There are no firewalls or AV enabled. Any help greatly appreciated while I wait on MS to give me a call back after opening this ticket.
