Port Forward & UPnP only works in safe mode

Xanathus

I've wracked my brain troubleshooting this out for the past three hours and have scoured the Internet (gooogle) looking for answers with no luck so now I'm falling back to asking random people.

Port forwarding, UPnP and DMZ have all stopped working on one single computer on my wireless network. However, they still work on other computers on the same network AND they work when I start this computer in safe mode with networking (running Windows XP Pro). I've tested with Windows Firewall turned off and don't have any antivirus or firewall applications running.

Here's a list of tasks running:

The main site is http://markgillespie.co.uk/ if you are worried about downloading an executable directly.

I have found that utility to be very helpful diagnosing UPnP issues that I had in the past.

I ran the tool and it informs me that "Windows is ready to receive UPnP messages, but they are never arriving. When the test tool runs this test, it requests to map a port on the router (TCP 1345), and checks the routers response, if successful, it then deletes this port mapping." From it's suggestions, I believe that I have a local firewall installed but I can't find it from the process list.

Is there any way to investigate if there's a local firewall installed on the computer?

Ok I *think* the problem is solved.

For reference to future generations:
I installed ZoneAlarm (the free version) and uninstalled it, it prompted me to disable my a Cisco VPN service which I did and now everything is working fine and dandy.
