I had to to a repair install on XP Pro, which appeared to work but now each time I open a Browser the net connection dies. I can "Repair" it and see that it's talking to SKYPE on my toolbar, but when I open Firefox or IE, it looses it's link to the Internet and SKYPE dulls out. Sometimes, I can "Repair" while the Broswer is open and get a connection for that session. Curiously, the network status remains connected and IP config still reports IP addresses to my router. I've tried removing the Network from Windows components in Add & Remove Programs, and reinstalling. No difference.
Microsoft TS told me that the problem was that I did the Repair Install with the Net connection still attached and that damaged the Network DLLs and I'll have to do a clean install. I think they're nuts because I can get a connection by clicking repair. It appears the DNS is not working properly in the computer and just refreshes for one session.
Any suggestions about how to clear this problem without doing a clean install?
