Outlook Express has mail checking problems on one computer. Fine on others

[BobTheSlob]

The error is this

The connection to the server has failed. Account: 'mail.bellsouth.net', Server: 'mail.bellsouth.net', Protocol: POP3, Port: 110, Secure(SSL): No, Socket Error: 10061, Error Number: 0x800CCC0E

It works on my other 2 computers, but not the one I'm writing this on. So what's the error telling me? I gotta fix this.

Come on people, this is my mom's computer. Help me, and her, out.
