We solved by doing the following:
On the FOG-Server install Winbind:
sudo apt-get install -y winbind libnss-winbindEdit the Samba config:
# /etc/samba/smb.conf [global] ... workgroup = <domain/workgroup> ... wins server = <ipofyourwinsserver> ...Edit the nsswitch config:
# /etc/nsswitch.conf hosts: files dns winsReboot your server.
On the Windows 7 clients we had to add the following firewall rule:
netsh advfirewall firewall add rule name="FOG Service" dir=in action=allow remoteip=<ipofyourFOGserver> protocol=tcp localport=445That worked for us.
