Currently running 2 windows 8 computers on my home network, both running as media servers through the homegroup, with 2 xbox 360's and a win 7 laptop connecting to them. Everything works fine with the exception that every so often (2-3 days) both the xbox's display the "No videos found" error when connecting to the one PC. I then have to go and select the "Allow all devices...." under homegroup, to fix it. This only happens with the one PC, and I have left and rejoined the homegroup, yet the problem persists. Any help would be greatly appreciated.
