 Posted: Mon Aug 06, 2007 2:18 am Post subject: Help with configuring DNS behind the firewall |
 |
|
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.

Yes, but you don't need the MX record internally. |

In the Public DNS for the email domain hosted by your Exchange server. |
Usually this zone is hosted by the Domain Registrar.

You usually only see these events if you have two DCs and they point only to
themselves for DNS. If you have two DCs, point each to the other for
Preferred DNS and itself for Alternate DNS.
