I have no idea why its doing this or what's wrong.
Suddenly our company Windows 7 laptop stopped sending and receiving emails. The problem it gives in outlook is that a connection cannot be made to the servers.
This error is replicated in Thunderbird and other email clients. Even pinging/telneting on the ports 25, 110 etc don't seem to work.
We have genuine windows 7 but unfortunately the laptop didn't come with an installation dvd so we cannot reinstall windows unless we order a dvd. I'm sure this is an issue with something other than the windows system though.
Laptop: HP ProBook 4320s (no recovery partition afaik - there's a HP Tools partition) Error: "Could not connect to pop.domain.com. The connection was refused."
We have many computers (windows and mac) connecting to the mail servers on a daily basis, so there's nothing wrong with the server.
If you need any more information then please let me know.
