DNS setup scenarios

I've read of 2 ways to setup DNS for Active Directory.  1 On the fly - when prompted during DCpromo. 2. Setting up DNS on a 'stand-alone' server- (I assume that's a serverwhich is not a domain member) and then running DC promo.  What's the preferred method of DNS setup if the PDC upgrade is just going to be temporary and we will eventually have 2 DCs which are clean installs? Are there any reasons why you would do it one way or the other way?

Either way is fine. # 1 is probably easier.

You eventually want to have the DNS service running on all your DC's

Do you have a DNS server on your LAN already?

We have but they are static and will have to forward to them for access to resources outside our domain.  I'm wondering if there is a situation why
you would want the DNS server on the DC?  Or why you would want the DNS server not to be a domain member?

Microsoft requires that a DC have access to a DNS server.  Usually, this means DNS will be installed on a DC, and then usually on *all* DCs.  Since AD is tied so closely with DNS, having DNS installed and running on every DC helps to prevent lookup failures in the case of non-AD related problems, like network outages.

I would agree that your option 1 is preferable.

Option 2 can be used, however, with a non-DC Windows DNS server, or a non-Windows BIND DNS server (I forget now exactly which version of BIND is required .. 8.6 or newer?).  In this configuration, with a stand-alone server (that meaning a member server, not necessarily a non-domain member), no DCs are *required* to be DNS servers.

But, as above, being that AD and DNS are so closely linked, I prefer to have all DCs also be DNS servers.

Option 3, which they made us do in class, is to install DNS on a member server first, get it fully functional, *then* run dcpromo.  The benefit of this is that you learn to get all the ducks in a row, so far as reverse lookup zones and PTR records are concerned.  Or, the wizard will do it for you just as well.  While this is another way to do it, I don't see any benefit for it outside of a classroom environment.
