Unable to Reach Win 8.1 License Server

I'm running a ver. 12.2.0 license server on a Win 8.1 Home box (machine name 'quantum').  The install seemed to go cleanly, and I've also installed the license file.  I get the following error when trying to access the server from a Win 7 box running HW ver. 13.0.112 on the same local network:

I get a similar error on a Linux box.  I am able to ping the server and file sharing works both ways between all the machines, so it's not a general network configuration problem.

I would guess that the built in firewall on the Win 8.1 server is blocking incoming data on port 6200, but I assume that should be handled during the license server software install.  I've always run servers on Unix/Linux machines in the past, so any help would be appreciated.
