A new install of Exchange 2013 into a domain which once contained and SBS 2003 server. (SBS removed before Exchange installed).
We are having occasional problems with the Transport service. It works fine for a few hours then starts responding with 4.3.2 Service not available.
The Transport service IS STILL running at this stage, and restarting it makes mail start flowing again.
We also have (possible related) 3 application errors from time to time
