Hello all, I'm running Windows7 Ultimate RTM build 7600 - Assigned to Homegroup I've looked through about as much of these threads as I can today, so hopefully this isn't a double post. I'm trying to share my media to my xbox360 via my wifi network at home. Problem I've been having is that all my options to turn on media sharing are un-selectable in the Homegroup settings. If I go into my music folder and right-click a song, then go to "share with" it's defaulted to "Nobody" and I can't change that. I click on Homegroup but it's reverts back to "Nobody". Media Center also fails when it's attempting to configure the extender (xbox360). It's also worth noting that I started to have this problem when I upgraded to the RTM build, I was running on the BETA and it all worked great. Nothing on my network has changed, everything outside the OS change is identical. Thanks in advance.
