We have a fairly small number of servers here at work at the moment and I
think I forsee a couple of potential problems with the DNS set up.  A bit of

We own the domain braytoncollege.org.uk (but it's not delegated to any
servers we run, but to a webhosting provider).

We have two domains at the moment, one is Windows 2000 AD
(student.braytoncollege.org.uk), and one is NT4 (ADMIN).  We're going to be
upgrading the NT4 domain to Windows Server 2003 in a couple of weeks, and
we're wanting to put it as a new tree in the already existing active
directory.  Does that mean we'll have to call it
admin.student.braytoncollege.org.uk? (student.braytoncollege is the root of
the forest), or can we call it admin.braytoncollege.org.uk?

What would happen if, in the future, we set up another domain called just
braytoncollege.org.uk?  Would the two subdomains work with it, or would it
cause problems?

Also, what would happen if all our computers suddenly had an internet
connection?  I have first hand experience of what happens when you give your
AD a domain name which is in use elsewhere on the internet - you get the
domain controllers trying to update the DNS servers which have control of
the domain.  It was a bad decision on our part to call the domain what we
did (but bad decisions are nothing new here).

What would you guys do to get around this?  Or am I worrying over nothing?
