Hello, I recently had my Dell reconfigured so that it went back to it's factory standards that it came to me in. Basically, All my hdd information was wiped with the exception of any already installed factory programs like Windows XP etc. Anyways, after I had done this and got my computer back up and running. I couldn't get both of my email clients to work. They are Outlook Express and Thunderbird. Thunderbird worked before I reset the computer back to it's factory defaults. Now, however, it won't work. I get an error from both clients basically telling me that the password was refused by the servers that I tried to connect to. I used two separate email addresses to try and connect to two separate POP servers. (Note; I only added two separate email addresses on the Thunderbird client.) I thought that it may have been the host file, but I removed the host file from the WINDOWS folder and still continued to get the same errors. I then tried turning off my Windows firewall and that didn't work either. I allowed both clients on the exception list on the firewall, and I even turned on the email client settings in the start - control panel - security center - Windows Firewall - and clicked the advanced tab and hit the settings button next to Local Area Connections. Basically, I'm stumped as to what the problem is. I thought it might of been my router, but I don't think so as I don't believe it's been changed recently. I believe it's my computer too and not just some closed port. Like I said, it worked yesterday, just now it's not cooperating. Any help in this manner would be much appreciated. Thanks again, Tyler P.S. I don't believe there's any malware or anything else that would be preventing the email clients from working, as I have just already reset my computer back to it's factory defaults. This is the first time that I can remember this happening like this.
