I had a server running on Win2k3, worked perfectly, had ace and isladual, etc now that box to a crap and I loaded it onto a new box with Linux Mint 8 on it, copied the required windows directory onto it and what not, it starts and says it is running, but.... It doesnt show on the server list, the ports are all forwarded correctly, as this box is in a Virtual DMZ. Any ideas on what could be the issue here?
