Service Pack 3 problem

I have an issue with my computer when I install service pack 3. I was running on service pack 2 (XP) and purchased Grand Theft Auto 4. The game however requires service pack 3 to play. So I installed SP3 and GTA4 and started playing. Eventually when I was over it, I exited the game and wanted to check my mail and realised that my internet was not working. Confused, I went to check my other PC which had perfect Internet. The router also showed that my PC was connected. I checked my Network Connection and it showed that it was indeed connected. For some reason however, I still could not browse the internet as it showed a "Cannot display page" error everytime I started my browser. I tried repairing the connection and installing the router drivers again but my problem was still not solved. I even tried creating a new connection but nothing happened. Any ideas how I could fix this because I really want to play GTA4 and have my internet running on SP3. I had to revert back to SP2 in order to get my internet connection working again.

What firewall are you running?

Ok will try that thanks. But I have to re-install everything first and will let you know.Am running Sygate Personal Firewall, Anand. I already checked it though. Don't think that was the problem but I can't be sure.

check windows firewall did not get re-enabled.
