I have a problem with Port 25 on one computer on the network. Case: corporate LAN, Windows 2000 Clients, and W2K Servers, Port 25 Open.
I have a small smtp utility for a specific task ('Advanced SMTP'), and it works on all computers, but on one it fails. Besides this, the computer is working great, it's the latest-fasted HP, configured the same way as the others.
Do you know what's causing this, and how to 'open' Port 25 (or fix it the problem other way)?
