Has anybody been using the MCE Plugin reliably with Xbox 360 MCE Extenders? We have one MCE Server which works fine with the Wiser, but each of our 3 extenders can access the plugin and be configured OK, but then sit in an endless look trying to connect. We have the server on a domain and I wonder if this is some strange permissions issue on the extenders, or even a firewall issue? Does anyone have any experience with this? At some point, one of the extenders did make a connection, but no longer! It is disappointing, since one of the Extenders drives an LCD behind a kitchen glass splashback and it looks pretty impressive - pity it can't connect to the Wiser GUI. Is there any diagnostic capability available on the plugin?
