After restarting my HP computer to factory settings to prevent numerous crash
dumps, my email account does not work. I get "can't find POP3 server."

The host 'POP3' could not be found. Please verify that you have entered the
server name correctly.
Account: 'POP3', Server: 'POP3', Protocol: POP3, Port: 110, Secure(SSL):
No, Socket Error: 11001, Error Number: 0x800CCC0D

How should I configure the computer.

Also, there was a security setting that would lock an an idle computer. I
lost that feature, how do I get it back?
