I have spent hours today on this and cant figure it out so I am seeking help here...
I have been running upnp server with MC for 6 months or so with my MP101. Has worked perfectly for months. I use it daily.
However, it suddenly stopped working this morning. Of course this was right before my daughter's birthday party where I needed the MP101 for the music.
I have not made any changes to Media Center and the upnp server is running as always. The MP101 finds the Media Center upnp server but it is "Unable to connect". After that, it continues to be able to see the server but not connect.
The only recent change I have made to anything is to add a switch to my network so I could have a couple of devices permanently connected. Everything else is working perfectly and the devices attached to this new switch work fine.
In the end, I did an emergency install of Twonkyvision which also worked just fine. But my MP101 continues to be "Unable to Connect" to MC's upnp server.
Does anyone have any ideas which might be helpful?
