I have two server behind the firewall, both running windows server 2003.

server1    192.168.0.1        domain controller & DNS server (configured as
mydomain.com)
server2    192.168.0.2        exchange mail server

Am I correct to say that I need Host A record as well as Mx record
configured in order for the mail server to work?
If so, where should I add the record to?

so far, I have two entries in my forward looking zone which I am not sure if
they should be there:
_msdcs.mydomain.com
mydomain.com

I seems to have read somewhere that one should  not add anything with
"mydomain.com" in the forward looking zone when the server has an internal
IP. Is this correct?

I am also getting the Event ID 4015 in the event log which says:

============================================================
Event Type: Error
Event Source: DNS
Event Category: None
Event ID: 4015
Date:  5/08/2007
Time:  10:05:13
User:  N/A
Computer: DC
Description:
The DNS server has encountered a critical error from the Active Directory.
Check that the Active Directory is functioning properly. The extended error
debug information (which may be empty) is "". The event data contains the
error.
============================================================

Can anyone suggest where I have gone wrong in the DNS or AD configuration?

I went through quite a few technet articles but so far has got nowhere.

Any suggestion?

Thanks in advance.
