I am a network admin running NT 4.0, SP 6a. I have a workstation where MS Internet Explorer gives the following message when it tries to go to a website, "An internal error occurred in the Windows Internet extensions." I get this message for IP addresses or FQDNs. None of Microsoft's Knowledgebase stuff seems to cover this problem related to NT --lots on 95, 98, Me - but I got an NT shop. I have reinstalled TCP/IP, reinstalled NT, winsock is where it is supposed to be. In DOS, I can ping websites and get a response, so I think TCP/IP is working, and I can see other worstations on our intranet, so IPX is working. Nothing new was done to this workstation to start this problem, it just like started doing it all by itself. Any thoughts?
