Port 25 hijacked

Since I installed a piece of software (to remain polite...), the port 25
on my machine has been blocked and this has nothing to do with my ISP, I
can no longer access my router. Booting with a different OS on the same
machine confirms my access has not changed.

Uninstalling the software does not resolve the problem. How do I
identify the culprit driver or software setting?

Regards

Take a look at TCPView on the following page. It will tell you which
processes are listening or using each port.

Thanks Oli, I will keep this handy but I must confess I was left
confused. After researching further, it appears this upgrade totally
prevented all communications with my router, both out and ingoing. Could
not even access it to check its settings but I knew they were correct
since the other machine on my network kept working normally. So somehow,
altough all network settings on this machine remained unchanged, it
stopped communicating and this was not a hardware issue since it works
normally when I boot on an other partition.

I realize those symptoms are difficult to troubleshoot since there may
be several causes but what services should I typically show on tcp view
? Which ones might be suspiciously missing or present ?
