help with DNS configuration

[Guest 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.

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.
