Worked with Dell for an hour last night on a rebuilt PC. IE will not work - cannot find page error - but we get good pings (all 4 replies received back) and Outlook mail is working. We checked everything I could think of and finally came down to running some/all of these utilities:

LSPFix.exe
WinsockFix.exe

Or installing SP2 and/or using FireFox. This is a client's PC, and I think he feels that it should work exactly as it did when he bought it. I used all the factory disks and everything seems to work great except IE.

Suggestions before I do any of the above?
