Is it possible to add a tertiary (3rd) DNS entry via GPO?

Hello All:

I am in the process of installing some mass-management software (sms-like) but until that's in place, a new issue arose which I need to immediately tend to: our DNS server is dying.

As a result, I wanted to put in a 3rd DC/DNS server, add that to all users ip configs, then remove DC2, and re-edit everyone's ip config's to show DNS3 as DNS2.

In more detail:


what I want:
DNS2: --dying
DNS3: --new one

Then take out DNS2 by using dcpromo and de-promoting it to nothing, then turning it off.

so I end up with:
DNS2: --new one

Can I do the above scenario via GPO? If so, how? This question is urgent so I am assigning it 500 points!!

    There is a setting in GPO for DNS servers.
    Computer Configuration -> Admin Templates -> Network -> DNS Client

    The included description states:

    Warning: The list of the DNS servers defined in this setting supersedes DNS servers configured locally and those configured using DHCP . . .

    So it sounds like this will do what you are lookiing for.

    Why don't you just use DCPromo on DNS2, demote it, then take it offline.

    Then bring up DNS3 but call it the same as DNS2, and replicate the zones again.

    Seems easier to me.

    I hate to ask, but why aren't you just using DHCP for DNS.  You can specify the dns servers and order much more easily there.  For the duration of your experimentation you could also turn the lease time way down to allow changes to occur rapidly.

    Isn't that GPO only for Xp? That's what is says in my 2008 R2 AD servers. If it were to be set, I don't expect it to work for other 2008 servers or anything else, except XP. Am I wrong?
