If you're trying to use Gamespy3d to search for NS servers, it will appear that you are getting a no response from ALL ns servers (ping shows 9999), it will still show the map and number of ppl playing tho.  I have not a clue why gamespy3d is doing that :/

However, you will be able to ping NS servers using gamespy3d once flayra is able to get the server patch out.  I tested it, i was able to ping fist of ra server when it had the patch.
