help with DNS configuration

[Edward]

I have a domain controller IP 192.168.1.2
I now try to set up an exchange server on another server 192.168.1.3
For some reason, the exchange server could not see my domain controller.
"dcdiag.exe" gave the report below which I suspect is due to DNS
configuration error.
Any help or suggestion?
(NB: my DNS server is also my domain controller and the forward looking zone
is pointed towards my ISP's DNS server)

Thanks.

===== dcdiag.exe report below =========================

If there are problems accessing this directory server then you may
need to check that this server is correctly registered
with DNS

This may limit some of the tests that can be performed.

Are you running dcdiag on this server, or on the DC? Run it on the DC. Run
netdiag on the would-be Exchange server. You might also post an unedited
ipconfig /all from each server - and mention whether your workstations are
having any problems communicating with the DC.
