For some reason, after a couple of hours working, my Denon 3808 loses connection with Windows Media devices on my home network. All my other devices (PCs running either Vista or Windows Home Server) can both serve and connect to each other without problem, but the Denon seems to simply fall off the network after a while. The symptom is that after playing streamed files, there will come a point when the Denon cues up the next track, but it either never starts (normally on the Denon's display, you see the buffering go from 0% to 100%, and once it reaches 100%, the track starts playing), or it starts, then the buffering falls back to 0%. Edit: I also see a "Server disconnected" message displayed on the Denon. At this point, if I search the network from any of the PCs, I will see the other Windows Media devices, but the Denon 3808 has fallen off its perch - it's no longer listed. The workaround is to recycle the power on the Denon - that will cause it to reconnect to the network and carry on. But this is hardly the most smooth user experience. I have the latest firmware (2.01) and the feature upgrade applied to the Denon. Strangely enough, Internet Radio stations work perfectly, but streaming from other Windows Media devices on my home network does not. Does anyone have any idea on what might be the problem? Thanks.
