The fix has worked for me and most people i've talked to, but try this...
-In Gamespy (in the Renegade room), click on the arrow to the left of where it says "Room Name"
-Select "Advanced Filtering"
-Click on it again, and select "Enter Advanced Filter..."
-In the text box, type in "dedicated=1", and press OK
If you still have problems, check several servers. Alot of them are set up without a connection setting.
