Good afternoon, I am currently using Windows 7 X64. My wife recently purchased me an Xbox 360 Elite for my birthday, but I am having some problems setting it up as a media extender. (to put it mildly) When I go into Windows Media Centre I can immediately see the Xbox with an option to configure, so I jump through the hoops and enter the number from the Xbox into Windows media Centre. I then get the message: Configuration Error An error was encountered while configuring your computer for use with this extender I have followed the steps at (http://support.microsoft.com/kb/932342) several times but removing the certificate and Restarting the Network List Service does not appear to work. I have tried everything again with the firewall and antivirus off but I still get the same message. If anyone can give me some help it would be appreciated.
