Hello Bob,
First I recommend you refer to the following information to your questions:
1. I guess I should start with the basics by asking if it possible to have
one DC back up another?
A: Yes.
2. By backup, I mean that if one DC is shutdown, can users still log on to
the domain by somehow automatically finding another DC?
A: Yes.
3. I'm thinking this is possible by configuring another machine using the
"configure your server" wizard called "Creating an additional domain
controller for an existing domain".
A: Yes.
4. I would think DNS must be in place on the BDC so that client machines
can find the BDC when the PDC is shutdown.
A: You can install DNS on the second DC.
5. I suspect that my GC is not being fully replicated (if at all) to the
BDC because when the PDC is shutdown, I'm unable to use AD-U&C to change
user passwords or create new users. When I try this, I get messages that
the global server is not operational. Using "AD Sites and Services" and
viewing "NTDS Settings" properties of each DC, I see that the connections
tab has the other server listed for replications to-and-from. I notice
however that the "Global Catalog" check box on the "General" tab is only
checked on the PDC; not the BDC. I don't know if that is good or bad.
A: If in a single Forest, a single domain, you needn't worry about GC as GC
only is used in a complex AD environment. You can leave GC alone.
Regarding your scenario, I recommend you setup the shares for Roaming
Profiles and Redirection Folders on a File Server rather than DC.
In the meantime, I recommend you first read some articles to have a clear
idea about AD and DNSR knowledge before you configure the servers:

domain:
