Windows 7 SMB Sharing to ATV2

Hey there!

I have a problem with setting up my Windows 7 Partition (Bootcamp) on my Macmini for ATV2. With OSX Lion via AFP it works very well, but on my Windows Partition i can’t get it to connect. I have the correct Sharing PW from my Home Network Settings and all the other correct Logins etc, but every time i try to test the connection i get a Error 13, Permission denied.

Of course i know, that i could just use XBMC for my SMB Sharing, but that doesn’t work properly with Subs, and most of my files are with subtitles.

What am i missing? 

I appreciate the help!
