Good Day All,
I am encountering a very bizarre 'condition' in that it appears as though one of my remote branch exchange servers is no longer listening on port 25? ?
Windows 200 Server SP4
Exchange 5.5 SP4 (yes I know...it's OOOLD :)
Here is the strange part? All Microsoft Exchange Services are running but when I run "netstat -an" the subsequent port listing reveals that port 25 is not listening? I can certainly confirm that the Microsoft Exchange Message Transfer Agent service is running...
Also...I have had a look and can confirm that there is now no longer any Anti-Virus software running on the machine.
Running a telnet to the local machine from the local command prompt confirms my predicament :(
"telnet 127.0.0.1 25" returns an "unable to connect to host on port 25: Connect failed"
Any ideas, I am truly stuck and as is always the case this is very urgent as the server caters for all of the staff at our Head Office site!
Thanks in advance
