WORKING: Network shares now displayed on Vista Media Center Extender!!
For all of you guys who haven't been able to get your vista network shares to show up on your vista MC and your Extender (i have spent so long trying to find a solution to this problem by trawling the net - with no joy.....) - i finally found a solution to the problem myself!! This works with either the MKLINK symlink or PUBLIC shortcut "solutions" mentioned on this thread - with these additional steps on the REMOTE PC hosting the network shares:
Click Start, Run, then type secpol.msc Edit this value - "Network access: Shares that can be accessed anonymously" and add your share names (e.g. SharedMovies) Edit this value - "Network access: Sharing and security model for local accounts" and select the "Guest Only - local users authenticate as Guest"
