I am using XP with SP2. I upgraded from SP1 to SP2 and that's when the problems started. I have disabled the Windows firewall and stopped the service and have disabled it through the group policies page. So Windows firewall shouldn't be issue, but I have a suspicion that it's still the culprit somehow. The source of the problem has to be somewhere on the local machine because I have the problems on any network I attach to, even my home network where I know nothing is blocked.
Unfortunately, I don't ho to resolve this issue. Does anyone have any suggestions on how to find out what the exact problem might be?
