SubDom host lookup prob from main Dom hosts..

[Hutch]

Hi..

I'm new to DNS so it wouldn't surprise me if I've REALLY messed up here.

I have one w2k DNS server for mydom.com, lets call it dnssvr1.mydom.com.
This has about 30 hosts using it for DNS.
I also have 3 other DC's for domains: sub1.mydom.com, sub2 and sub3.. etc.
These other 3 DC's have dnssvr1.mydom.com as their primary and only DNS
server.
When the DC's were initially set up and pointed to dnssvr1.mydom.com
subdomain folders were automatically created in the DNS server. I have not
done any additional setup on them.

Now.. if im on dnssvr1.mydom.com and I do an nslookup on any of the hosts in
that domain say 'nslookup host1' I will get the reply:
Server: dnssvr1.mydom.com
Address: 10.10.0.10
Name: host1.mydom.com
Address: 10.10.0.20

BUT.. and this is the problem.. If I nslookup on any hosts in the subdomains
I don't get an answer unless I include the subdomain.
So.. 'nslookup hosta.sub1' returns:

Server: dnssvr1.mydom.com
Address: 10.10.0.10
Name: hosta.sub1.mydom.com
Address: 10.10.0.30

So.. 'nslookup hosta' returns:

Server: dnssvr1.mydom.com
Address: 10.10.0.10
*** dnssvr1.mydom.com can't find hosta: Non-existent domain

The reason I want/need this to work is that I'd really like to totally kill
any NetBIOS/wins type traffic in our network and have everything refer to
DNS.
Is this possible? can the DNS server be set so that if it cant find a host
in its primary zone it checks subs too?

TIA ,
Hutch

That's your client that gonna ask with one extension and
then with another. You have to look at the TCP\IP
properties, DNS tab. You can herre add as much as DNS
suffixes you want. Your computer will then prompt the dns
with these suffixes in the order you entered them. First
it will ask for hosta.mydom.com and then
hosta.sub1.mydom.com.
You can give your computers these parameters via DHCP also.
