Re: DNS A Record Order.

Hi All.

I have an issue with MS DNS.

We have 3 subnet A=192.168.1.0, B=192.168.2.0, C=192.168.3.0

Subnet A and B have DC's .5 in each.

The resolution of the domain name foo.com points to the 2 dc's

In subnet A and B they subnet prioritization gives the correct host
name for each site.

The issues start with subnet C, this is a remote site and can only
access subnet A

We have turned off round robin DNS.

I would expect that then the DNS server would return recored in the
order that they are created. IE the first in the list. This is
correct, if the DC in subnet A is on the top all is OK but from time
to time it seems to reorder itself and the DC from subnet B is on the
top.

This breaks GPO deployment for subnet C. ie \\fooo.com\sysvol\.. etc
etc is broken.


Is there a way to "lock" the resolution order for the domain A
records?

This is a point I brought up for adding support for this to the new version
of Windows server (now in Beta) I'm keeping my fingers crossed for this.

At this time you have to rely on Netmask Ordering, and disable round robin.
If that doesn't work make static routes for all subnets or use the hosts
file. DNS kinda' just does what it wants to when it comes to sending out
records in a particular order.
