A recent update to samba screwed up symlinks for Windows machines.  Some 
web pages have incorrect information about how to fix this.  This is the 
correct information (but note that the first contributor on that page has 
"wide symlinks" which is wrong):

sudo gedit /etc/samba/smb.conf

Then I put this under the [global] section
Note: It's "wide links" and not "wide symlinks"

follow symlinks = yes
wide links = yes
unix extensions = no

Save it and then run this to restart samba.

sudo /etc/init.d/samba restart
