I had an issue with a friend's PC after installing SP2. I was able to browse the web for 2 hours but after the PC was idle for some 2+ hours I got the network icon on the system with the exclamation mark saying "limited or no connectivity". At the time there was no post for this problem and so I did a fresh install of XP Home (I did un-install SP2 and this did not resolve the problem). The next day (Go figure) there was a post about using the WinsockXPfix program. My question is has anyone had this problem and used the program to fix the problem?
