Travel Technology - Outlook Express: can not connect

I have checked all the settings within Outlook Express and they are identical to the computer that is working on the exact same cable. I can connect my other laptop with the exact same OE settings but can't get the other one to connect. I think there may be a general windows/ internet security setting that I don't know about. Any thoughts or suggestions on why I can't get my Outlook Express to run on this laptop. FYI, this is a personal laptop so I don't think it is work security setting that I can't change. Thoughts? Suggestions?

Firewall configuration?

What security software are you running (anti-virus, anti-spyware, firewall)?
What kind of mail server(s) are you trying to connect to? (POP, Hotmail, ??)

I figured out. it was the norton anti virus that was messing with it! Thanks anyway for the help!

Norton has to be the worst AntiVirus program ever invented.
