Windows XP Home, SP3
Windows Media PLAYER 11
.NET Framework 1.1 Service Pack 1
Linksys Router BEFSR 41 with latest firmware update
Xbox LIVE works just fine, I have no problems with it. All the required services are running, and windows firewall is allowing the required ports. I have enabled UPnP on my router. I have updated my DRM files using the walkthrough provided elsewhere on this site to no effect. When I go to enable sharing in WMP11, the xbox DOES NOT show in the dialogue box to allow it to share. If I open the command prompt, I cannot ping the IP of my xbox; the request always times out. I have combed the xbox.com forums to no avail...nothing seems to be working. I have also looked through some of the posted topics on this board, and they haven't yeilded any results for me either. It is possible that there is a very simple step that I am missing, but I just do not know, and I am ready to drop-kick the 360 over this issue.
I am at a loss for what to do. Any help would be greatly appricated.
