[Samba] BIND Problem on CentOS 6.3

I've set up a Samba4 PDC on a CentOS 6.3 and so far it's up and running, 
following the howto on the wiki.
This means I've joined the AD domain with a dedicated Win 7 virtual machine, 
I've installed the RSAT tools on that machine and I can administrate the AD 

I've set up this PDC in an existing small network with an AVM FRITZ.BOX adsl 
router, which is already the primary DNS nameserver. Within this network 
there are some more (Linux-) servers which are not part of the AD domain:
- for example    srv-alfresco.fritz.box

When I now try to connect to one of those servers from the dedicated 
machine, this is not working. The domain name can't be resolved.

When I open a terminal on that Samba4 PDC and try
- ping srv-alfresco --> unknown host
- ping srv-alfresco.fritz.box --> unknown host
- dig srv-alfresco --> Status NOERROR, IP resolved
- dig srv-alfresco.fritz.box --> Status NXDOMAIN

When I remove that specific includes from the named.conf the above commands 
are working, but naturally the PDC is not working.

I'm sorry but after a couple of days doing around I have no idea how to 
solve that problem.

Any help would be appriciated.
