NSLOOKUP is failing because you do not have a reverse-
lookup zone. This, in itself, will not stop AD from
working. But for piece of mind and troubleshooting I
always recommend a Reverse lookup Zone. To simplify
administration, use a subnet that encompasses all of your
network. For example, if you have four class-c nets,
create a class-b reverse zone.

--
Going back to another point you made, do not disable the 
DHCP client service on the DC.  Netlogon uses the DHCP 
client service to dynamically register the SRV records 
(every 12 hours by default, but you'll be hard-pressed to 
find this documented).  If it's not running, you won't 
register SRV records.
Perform the following on the DC:
-- Set DHCP service to automatic and start
-- Ensure that the DC is pointing to it's own IP for DNS
-- Ensure the DNS zone accepts dynamic updates
-- Stop netlogon
-- Start netlogon
-- For good measure, type ipconfig /registerdns too ;-)
Also ensure that the workstations are configured to point 
to the internal DNS server.
Once this is done, install the support tools on one of the 
clients and type nltest /dsgetdc:domain-name.com.  If the 
dsGetDc call succeeds, then the IP-DNS locator should be 
able to get enough info to work.  Logoff and Logon again.
--
Check that both DNS servers are listed in the Name Servers 
tab -if they're not, add the appropriate servers.  The 
Name Servers tab is what defines the NS record and 
therefore which servers are authorative for the domain.
