I am unable to connect to my library remotely through another install of Media Center. Both the server and clients are running the same version of the Windows application. When I attempt to Connect to Remote Library using the correct access key, I get a progress dialog that MC is downloading the library and it goes all the way to completion before erroring with the message: “There was a problem connecting to the server. Double check you entered the correct key and that the server and your connection are working.” If I retry, MC doesn't even try to download the library again, it just shows that error.
However, I can connect to the same library server via WebPlay and WebGizmo from the same machine on the same connection. I can connect, browse, and play tracks and playlists flawlessly through this interface. I am also able to connect to this library using Android Gizmo from the same remote network using the same access key.
That it's working through other clients should rule out some of the most obvious possible culprits. I have performed a ton of the standard troubleshooting steps anyways (turned off antivirus/firewalls, checked port forwarding, reset access key, change browser type, etc.) but obviously I can get to the remote library just fine, it's just the main Windows MC client that refuses to connect. Also, the fact that MC initially connects to the library and downloads it completely seems to indicate that MC is reaching it, but failing at some point subsequent to the download.
Any ideas what's going wrong here?
