Before today I would connect to shares on my Windows 7 computer from XBMC. Now when I try to add a source I get this lock preferences screen popping up and it won't accept my password. I know the password is right. I have never seen this screen before.
I have tried the steps in the thread below about XBMC not authenticating to Windows 7. I have even tried reloading XBMC fresh, but I get the same thing.
I am thinking it is my Windows 7 box, but I don't know what could have changed between now and a couple of days ago...
