Try using "nslookup" by IP and Name (full network name, such as
"server34.myinternal.domain.com" and NetBIOS Name, such as "server34"). Note
which DNS server you Query and also try to connect to the other two and
Query them.
Also check the Secondary Zones on the Primary DNS servers, do they list all
the data from their primary, i.e. has the Zone actually replicated to the
other DNS servers.
Basically you want to test each DNS server and compare responses and try to
track down where things hang.

Oh wait I just re-read your response. I am not talking about which DNS
server your machines Query (TCP properties). I am talking about the DNS
SERVERs that are responsible for your Domain Name Resolution. Do not confuse
this with your ISPs DNS servers.
NOT THE SAME.
For AD to Work You Must have Your OWN Windows DNS SERVERs.
You said/suggested that each Subnet had it's own Authorities DNS server.
These are what you need to check.

Each Windows AD domain will/should have a Primary DNS Server that holds a
Master Copy of all the Zone Info, this will be one of Your Machines on the
same piece of wire as your other machines. Meaning your TCP settings should
list a DNS server on Your Network with a Private IP not a Public IP
(Internet DNS).

Again use "nslookup" which DNS server do you connect too. One inside your
office or one outside? If outside your Office, how is it supposes to know
which resources you have and what they 're named?
