So, I found a friend who still had his nwn discs so I was finally able to install the game without pirating, but now I have a new problem.

The network restrictions at the college I attend prevent me from connecting to gamespy and loading the server browser. However I can still join any public server directly provided I know the servers IP address.

So basically now I'm looking for any sites where I can see what servers are up and running so I can find servers to join.

Although it is not a straight out server browser on the webb you can easily see servers and their status by adding favourite servers to your own profile page at X-Fire.

Here is an example from my own profile page. Scroll down a bit and you will see all my favourite servers.
http://www.xfire.com/profile/superfly2000/

It is updated every 5 minutes or so I think.

On a guild page you can have even more advanced monitoring.

Click the servers on that page to see an even more advanced monitoring.

(Scroll down a bit on my guild page and look for the servers on the right hand side.)
