I have messed something up by trying to install Internet Connection Sharing and then trying to undo it and get back to where I was. The result is: (1) I can connect to the internet, but when I try to send & receive e-mails using Outlook 2000, it cannot find my mail server. This is the same with different ISPs. Then it reports a problem with mapisp32, and Outlook locks up. (2) When I try to open a web page with Internet Explorer, it fails, and makes Explorer crash.
Can anybody help with a diagnosis? I'm on Windows 98.
