Tested on a Win7 Pro computer and it worked number one in LAN. But when installing the server on the local server (windows server 2008 R2), I can't access on the local area network. This might be because of the the fact that Windows Servers locks every thing it can in network. I tried unlocking port 80, 8080 and 8090, but that did not allow access from the LAN. Could you please indicate all ports that are used by you're program.
