Jenkins on Windows no web GUI - can't setup

Question

Ive installed Jenkins on a Win2003 Server but when the install completes and attempts to load up the GUI in the browser it fails with a "Internet explorer cannot display this webpage message".

I've uninstalled and re-installed it several times, rebooted, re-installed the latest java but still no luck!

Hopefully someone can shed some light on what to try next or maybe even solve it.

MORE INFO:

I installed it a long time ago as a service and it was working. But the it then got put on the backburner and so was disabled. Its now wanted by the boss man so I went to the localhost and it gave the error even with the service restarted.

I then tried to stop the service again and services.msc threw up so error but with no details of note. So, I then disabled the service.

I rebooted and reinstalled it several times, and installed the latest JAVA update and still no luck.

On one occasion I managed to get the web GUI to start and then a message came up saying it was waiting for Jenkins to start up. After a period of waiting this timed out and IE returned the cannot find page error/message.

Ive tried reinstalling / uninstalling / rebooting / etc but nothing seems to make a difference.

In my experience once I saw that I couldn't navigate to localhost:8080 I just assumed it was a server issue. Given that I use WAMP on my Win 8 machine, I simply turned WAMP off...and it worked. Naturally this isn't ideal and when I figure out how to redirect a request from port 80 to 8080, I'll update my answer
