Windows 2003 DNS
Posted on 2011-10-03
Hi Folks, Wondering if you can help me, Ok the Layout,
Firstly its a split Brain as our Domain Name for our site is named the Same our active Directory FQDN, ie web: domain.com AD: domain.com ( This was implemented before I joined so not the best solution)
Internal DNS on Windows 2003. With External DNs Servers outside the DMZ.
Windows 2003 internal Active Directory integrated
DNs External Just Standard DNs Server`s in the DMZ
The issue I am having is in Relation to DNs for a Externally hosted website, http://www.domain.com ON the internal only and External works fine...
We Have A records for Both http://www.domain.com and http://domain.com
on Both internal and External DNS servers
However when it comes to http://domain.com The external server have a A record to resolve this and All works Fine,
When it comes to the internal DNS Server`s they have the Same A record for http://domain.com as the external,. But it dosnt resolve internally,
For Some reason all the DC Servers seem to Have A Records there also, And i am told this is a Part of Active Directory Intgrated zones
If I do a nslookup for domain.com I get the Web site address as I should from the A record, But for some Reason I also get all the Domain Controllers listed in under the nslookup
And when i check The DNS records themselves I can see, A records for the Server Name and one for Each under them for Parent Folder
Server 1 A record and IP
Also As Parent folder A record and IP Address (Under the First a record
Server 2 A record and Ip
Also as Parent-Folder A record and IP address
Any Ideas, how i can Fix the internal DNs Lookup for this record, as 1 server in the internal Network, Someone has IIS installed on it, and the WWW service. and when you go to http://domain.com its seems to only see this A record for this WWW Server (I am getting another sysadmin to Remove the www service from this internal Server) And not the outside http://domain.com A record.
Any way to fix this? Or Make it See the A record for http://domain.com?
I have tryed removing the Server a records but they return as they should.
