   Networking with DirectPlay and WInXP?!?!?!
    Im having trouble using directplay while running winxp, any time i try and host, i specify a port number, and it says cant host. The only solution i found is to specify port 0 and let it pick one for me.  The problem with this is how does the client know which port the host is running on?  If anyone can help me, please respond.Im using DirectX8.1 
  Just guessing here, but do you have Internet Connection Firewall turned on? If so, it may be that you have create a service entry and specify the port(s) you want to use in the ICF settings. ;  No, firewall disabled. Im not so worried about having to use port 0, because I think this would be a way to assure an open port on whatever system i run on.   I guess the real problem is how to get the client to search the ports for the host application.  So anyone with some source code, or help in doing this. Your help will be appreciated.
