Hey guys. I am having problems getting UPNP to work reliably on my windows 7 machines. I am running the PlayOn Media Server (http://www.playon.tv/playon) installed on one of my windows 7 machines (my office computer). Firewalls and AV are turned off on both machines. I am able to sometimes view the PlayOn server on the office computer from my home theatre PC (windows 7) but other times it doesn't show up or takes an awful long time to show up. I am using UPNPInspector (http://coherence.beebits.net/wiki/UPnP-Inspector) as a means of checking whether the HTPC machine can see the PlayOn Server on the office PC.
I'm using a D-Link DIR-628 router. Both machines are connected via wired ethernet. The router sometimes shows up in the list of UPNP devices but other times it doesn't show up at all. I'm not sure if this indicates anything or not. I have UPNP turned on on the router.
I ran the Internet Connectivity Evaluation Tool (http://www.microsoft.com/windows/using/tools/igd/results.mspx) on both PCs and both showed that UPNP was supported on both.
This has been puzzling me for quite a long time. Every once in a while, everything works great for a short period of time. Usually, however, the HTPC machine can't even see the PlayOn server on the office PC.
Does anyone have any ideas on what I can do to troubleshoot further?
