I think Rick has hit the main points. From my POV, the most important issue
is being able to constrain replication if you use multiple domains. If you
have a smallish environment and replication traffic is not going to be an
issue, stick with a single domain, or at most an empty root with a single
subdomain.

Rich,

Loaded question.  I've got a few minutes before heading off to bed to do
some reading, but I think you'll get more than enough response to get a full
view.

A few benefits (I suggest someone fill in some of the drawbacks, too)

1.  Separation of Schema and Enterprise administrator from rest of domain
structure, providing some degree of protection for key and sensitive
entities from the 'work' domains.

2.  Use of a root domain provides for easy expansion and acquisition by
adding a domain below the root.

3.  Provide for replication boundary of domain related data, thereby
reducing unnecessary traffic because domains do not replicate to each other.

4.  Create a separation of function or security based on password, account
lockout properties. (Do not in any way confuse a domain in Windows 2000 to a
domain in Windows NT 4.0.  Transitive trusts are automatically created
between domains in a forest.  A forest is more synonomous to a Windows NT
4.0 domain when viewed from a autonomous security context)

Hope this helps - and gets the discussion going....
