Hopefully the microsoft domain is a name that is not availible on the
internet, like mymsdomain.local. Then your microsoft server is known as
domaincontroller.mymsdomain.local.
Of course !
In that case you would setup a forwarder in BIND for mymsdomain.local that
points to the microsoft dns servers.
Ok, but I'd like understanding if:
1- for every query to BIND there is always a forwarding to microsoft dns
servers or if there is only a forwarding for queries containing
'mymsdomain.local' domain ?
2- If I configure BIND how you suggest me, can I not permit Internet queries
for ''mymsdomain.local' ?
3- Can you show me sample example of forwarding configure file for specific
domain, please ?

I'm using Bind9 for my name server (SERVER EXT) and to give name resolution

My domain is example.com:
www.Example.com
test.h...@example.com
This dns server maps only my pubblic addresses.
This server has 2 nics: internal + external ip address.
Some internal servers, as proxy or mail servers, send dns requests to this
dns server to solve names.
I have also internal MS domain (dns server is SERVER INT) which is
different from the other, it's created by Domain Controllers + AD
(activedirectory.com) and it's used to map machines into internal network.
Now I my email server or proxy server (which are in internal network) need
to synchronize time so they have to use my internal NTP server; these Linux
machines use 'SERVER EXT' in /etc/resolv.conf, so how I can indicate to send
request for specific internal name (ntp.activedirectory.com) to dns server
INT ?
I could insert it inot /etc/hosts but it's not dnssssss service !!!

domaincontroller.mymsdomain.local, your Bind name server will ask the
microsoft dns servers for the answer.
