Our office has 2 identical Dell Dimension boxes. Both have the same trouble with their respective user’s email. Outlook 2000 keeps giving the following error when attempting to send or receive email. “The TCP/IP connection to your mail server was unexpectedly terminated. See your administrator…..” I tried the same 2 users profile on a different Dell machine and they work fine! After several minor remedies that did not solve the problem, i formatted the hard drive and re-installed a fresh copyof all applications. Well the problem has not gone. I checked the server for permissions issues, no joy there. I checked Microsoft’s site for this error, but found nothing helpful. I am stuck now, the only thing i can think of is hardware, but the rest of the machine functions ok, including internet access. Please help!
