The two numbers will remain at zero as long as no one has joined your server. Users may not be able to join your server if:



1. You have a firewall that is blocking the vital Jazz 2 server ports.



2. You are serving levels with defective headers and in some cases, filenames.



3. You have limited access to the internet. This is most prominent with AOL and its parental controls; you must be on General Access to serve.



4. You are connected to a local network; local networks generally have an increased security against ports that allow file-sharing and increased internet protocol address use. You may optimize this from the main computer on the local network.



5. You have an OS not optimized for Jazz 2 (i.e. Windows 2000 is not ideal for games).



The problem you're having with serving may be anything from the severe problems, to the easily repairable problems; I don't know from the current specifications. Good luck in finding out what's wrong. Hopefully, you'll be able to serve.
