PORT 443 isn't working on 1 machine

[harveyetter]

No HTTPS items are working, instant messeger, aol, etc. I am guessing
they all use port 443. No firewall is installed. I did a virus scan
and spyware scan. Didn't help. It was running SP1, so I updated to
SP2 to see if that would fix it. It didn't. Every other machine in
the network works. What could be blocking this, is a file damaged? I
also ran the Winsock fix also. Please help!

Machine is now running XP HOME and now Sp2.

You say you are running Windows XP SP-2, but have no firewall installed. Do
you mean that you have turned off WinXP's built-in firewall?
