installing Symantec Mail Security for SMTP on Win2K Server get stuck when I have to configure the listening port numbers for SMTP, HTTP & HTTPS.
I leave the default ports (SMTP=25, http=8003, https=8043) & get this assage:
"One of the ports specified is already in use or invalid"
only when I changed all the ports I could get on with the installation but I couldn't change it back in the configuration screen so I had to uninstall it.
there is another mail relay installed on another machine in the network which would be shutdown once the new verison is up & running. I don't see any connection but anyway I even tried installing while that machine is turned off. same result.
I have no idea where to start...
