You really need to fix this. You have two ethernet cards, eth0 & eth1, 
do you really need two, could one be removed ?

If it cannot and you only need one, you need to change the 'interfaces' 
to only use the one you want.

Yes, they rather stupidly used to do that, though they now suggest that 
it isn't a good idea, but its a bit late now, just never use Avahi on 
any Linux machines and don't add any Apple machines to the domain ;-)

Some suggestions:

remove the 'luke' line from /etc/hosts . DNS should find this

Remove these lines from smb.conf:

server role check:inhibit = yes

server signing = auto

dsdb:schema update allowed = yes

winbind enum users = yes

winbind enum groups = yes

rpc server dynamic port range = 49152-65535

Change this line:

interfaces = lo,eth0,eth0:eth2,eth0:eth2,eth1

To this:

interfaces = lo,eth0

Try the Bind9 files I posted earlier

install a couple of packages that don't seem to be installed: attr
