I have a home network and unless I completely disable ESS's Firewall I cannot use WMP12 Remote Control feature. The machines simply don't see each others WMP to controll. The issue Is with Windows 7 and it has been checked. Using the Windows firewall works like a charm. Edit: The firewall log says it is blocking ICSLAP Outgoing Requests (UNPnP) to the WMP and From the WMP ok, there is no mistake here, it is a deliberate rule in ESS that prevents the comunication. WHY ON EARTH WOULD YOU PUT THAT RULE THERE? ARE YOU TRYING TO MAKE US ALL ANGRY AT YOU? there is a default rule in the firewall that says "BLOCK OUTGOING (AND INCOMING) ICSLAP (UNPnP) CONNECTIONS" but it is not limited to untrusted zones, NO it is a GENERAL BLOCK ALL RULE FOR ICSLAP... where is the danger that you made the rule block ALL TRUSTED AND UNTRUSTED? WHY NOT LIMIT IT TO UNTRUSTED AT LEAST? I really don't understand you guys.
