Hi, I've been up for days trying to get my XBOX360 to connect to Windows Vista Media Centre, with no luck. I already allowed UPnP, by unchecking the boxes where it says UPnP.. and thats what finally allowed my XP machine to be detected on the XBOX, but not Media Centre On the XBOX it says it can't connect to Media centre PC and to ensure my PC is on and connected to the same network, which it is. when I go into Media Centre on the media centre PC it says that it can't find the Xtender and to make sure UPnP discovery is allowed, which it is!. Iv'e tried to go into settings in media centre and add an Xtender manually, it didn't work..said it couldn't locate the XBOX360. I also disabled ess firewall and enable windows firewall on my XP PC..and STILL couldn't get XBOX to connect to media centre, why is this??. Prior to installing ESS I have never had this problem with Media Centre not working. On my media centre PC, which is wirelessly connected to my home network, I have Vista Premium running, AVG free and Windows firewall. Everything else works..my Vista PC's files,music etc shows up on XBOX, but Media centre won't work..very strange!!..and my XP PC is detected as well. I heard there is many bugs with this new ESS, and Group Policy Editor is NOT available with Vista Home or Premium!!..so should I give up and uninstall ess all together and just take AVG free and stick with windows firewall to solve this mess?. Even after disableing ess firewall and enableing windows firewall..media centre STILL won't work..so im left confused and tired of dealing with this. There is no basic functionality with ess.
