[Samba] gpupdate use wrong url

[basti]

I have done the bind config like Rowland's post.
The problem is still the same.

windows:
nslookup foo -> nxdomain
nslookup foo. -> ip of DC

in linux both is return an ip

Whats about the file named.conf.update in samba/private?

I have try to include in named.conf or in

dlz "AD DNS Zone"{
...
include ../named.conf.update
}
without success.

My bind log errors like
named[27869]: samba_dlz: starting transaction on zone foo
named[27869]: client 192.168.122.84#59657: update 'foo/IN' denied
named[27869]: samba_dlz: cancelling transaction on zone foo
