We began having trouble with our exchange server. 
For no reason we could pin down the OWA would 
throw up an error and stop the www service.  Being 
the slightly paranoid sort I downloaded Retina and ran 
it against the email server.  It showed the usual things 
but it also showed
Port 1058 - Nim
Port 1090 - Xtreme

Two other exchange servers show these ports open.
Port 1042 - Bla
Port 1059 - Nimreg

Katherine,

as Nexus said, use FPort (or similar) to figure out the service/task
associated with that port. My guess would be 1042 - dsamain.exe and
1059 - store.exe (which is the Directory service and the Information
Store of Exchange).

However, if fport shows 1042 - winshell.exe, or any other executable
an ordinary NT server doesn't have, then yank the box and
investigate.

Regards,
Frank
