Minimserver does not show on network

[bgladdy]

Sorry to post what should be an easy question but I've spent weeks without success.

I'm running Minimserver/JPlay on a 2 PC setup and cannot access Minimserver from network control points. I can access it via Kazoo on the local machine.

I have tried several control PC's with both Windows 8 and 2012 all with the same problem. All have two ethernet cards installed, one configured as default and connected to my home network, the other configured with static ip and connected directly to the Audio PC via crossover cable.

I've checked that Java is unrestricted in firewall. I was able to get it to work in only one test instance by completely disabling the Windows firewall. However I cannot get it to work in any other scenario or my preferred setup. Right now I even have that machine DMZ in the router but still no joy.

Not sure what to try next. Appreciate a pointer of what to look for next. Thanks.
