Manual: v5 - 230, v6 - page 139
Port 2903 is the "Listener" port for the Server, all the subsequent communication is negotiated dynamically in UDP land (not sure of the exact range of addresses), certain firewall configurations handle this better than others. Try using the Windows NT/2000 command line utility "netstat" with the "-a" command line switch to see what is going on. A good network sniffer may also help with this.
