Recently I have been nominated to take care of a network after a company that
we hired bailed out on us. I had some training in the past with windows
server 2000 but have forgotten alot of it by now. This is what I have.

I have DSL coming in to a modem/4 port router which is provided by the dsl
company. From there I have one ethernet cable going to a set of linked 24
port switches. All "admin" computers are wired to these switches including a
Windows 2003 server machine. There are also several internet access only
machines wired here for "clients" to come in and use. I also have one cable
going from the first modem/router to a wireless access point, which provides
internet and network access to any laptops that are brought in.

I have figured out that the server is a domain controller. It is running
only one domain which includes all "admin" computers. Somehow this server
also controls the "client" desktops which are in a workgroup. I know there
is a program called deepfreeze on the server which reloads the original
desktop on the client computer at each login.

My questions are:
Can the domain controller still control network access with this setup and
how?
How can the server have control over the domain and a workgroup? Or is it
just the one program that has control over the workgroup?
Is there a way to keep the admin computers seperated from any of the others,
but still have access to other admin computers and the internet?

Sorry for the long post but any help would be greatly appreciated.
