Louis, 

Changing interfaces to IPs instead of lo eth1 in smb.conf did the trick. Thank you for your help! 

Regards,
Jeff

this looks like a incorrect resolving.

Please take notice of the following.
1) check your /etc/hosts file
should be like :
127.0.0.1       localhost
192.168.0.1     dc1.your.domain.tld     dc1

2) check  /etc/resolv.conf
#
search rotterdam.bazuin.nl
nameserver 192.168.0.1
and/or
nameserver 127.0.0.1

3) check /etc/nssswitch.conf  like ..
passwd:         compat winbind
group:          compat winbind
hosts:          files dns mdns4_minimal [NOTFOUND=return]

4) to domain.local... should be avoided, since .local is an reserved TLD. for mDNS
but since you have it already, dont change it.

5) in smb.conf   dont use the interface names, use the IP adresses.
so dont use :
interfaces = eth0 lo
bind interfaces only = yes
but use
interfaces = 192.168.0.1 127.0.0.1
bind interfaces only = yes

There is a report of ubuntu incorrectly useing the interface names in samba.
I dont know if its fixed but please try the ip.

please check all above, if you change something, restart the services ( or the server )
and report back.

Best regards,

Louis
