I promoted the only server on my network to a domain controller via dcpromo.
The wizzard prompted me to setup DNS, which seemed to go off with out a
hitch. I also configuered dhcp. I don't have a problem finding sites on the
web, but when I do a nslookup on the LAN i can only resolve hosts that are
joined to the domain.

You're saying nslookup is only resolving IPs in your own reverse zone and
not the public side?

Is this Windows 2000 or 2003?
Is there a forwarder set?
Can you give us an example nslookup output please?
Are you only using your internal DNS on your machines?

Sorry about the lack of details, I'm still a little new to this.
I am running 2000 server. I do have forwarders enable and a couple forwader
IPs. When I do a nslookup on a machine that is not joined to the domain I
get "***server1.mydomain.com can't find computer1: Non-existent domain", but
if I do a nslookup for a machine that I have joined to the domain I get
"name: server1.mydomain.com
address: 192.168.0.1
It works fine. It seems like a rights issue to me, but I really have no
idea. Which is why I have brought my issue to you the experts.
Thank you in advance
 
I am only using my internal DNS on my machines. As a side note I can ping
host names and IPs with the -a switch with succesfull replys

I see. Then my next question is, "What DNS server IP address is the machine
that is "not part of the domain", using in it's IP properties?

Can we see an ipconfig /all of both machines please?

Believe me, it is NOT a rights or permissions issue. No such thing when it
comes to resolving.

This is probably because the non-member machines are not able to register in
DNS becaue you only allow secure updates, and the non-member machines do not
have the proper rights to update the secure zone.

Then it doesn't make sense. As long as all machines are only using the
internal DNS (no mixing up DNS addresse on the clients), I cannot see why
this happening.

Can we see the ipconfig /all please? It could also be a search suffix issue.

I believe you are on to something. So, because my forward/reverse zones are
active directory integrated machines not joined to the domain do not have
write acces to the zones? Does this mean I should give elevated rights to
anonymous account for both the forward and reverse lookup zones? If so,
would this require write access? That sounds a little scary, but am open to
sugestions. Thanks again to everyone who is helping me figure this out.

I think you can just allow secure and non-secure updates would do the trick
for the time being just to test it, instead of altering permissions. Once
you've verified that works, then you can try the permission route.

I'm not sure I'd allow non-secure updates or alter permissions. You can
always let DHCP handle the DNS registrations.

If that's the case, the clients will either need the Primary DNS Suffix set,
or the suffix set in NIC properties, or force DHCP to upate all clients.

I believe the option in the DNS tab on the DHCP Server Properties page
addresses this exactly. The "Enable DNS dynamic updates according to the
settings below:" option with the "Always dynamically update DNS A and PTR
Records" produces the expected updates. I have not tested this since all my
systems are a part of the domain but in my corporate environment DNS is
resolving Win98 and NT 4 systems that are not apart of the domain as well as
W2k and W2k3 systems. Unless there is a WINS server that is not listed in
our configurations that I don't know of.

That is exactly what I mentioned, "force DHCP to update all clients".

Just an FYI, the DNS tab in DHCP properties is actually Option 081.
