As Tom said - that document is outdated to the point if vast
incorrectness-like-stuff...
With ISA 2004, you only need ISA to be a member of a trusting domain if
you expect to support firewall client traffic.
Otherwise, you can RADIUS-auth to your heart's content.

I should have mentioned that I came across this document before posting:

http://www.microsoft.com/technet/prodtechnol/isa/2004/plan/securityharde
ningguide.mspx

"Determining Domain Membership

In many cases, you may want to set up the ISA Server computer as a
member of a domain. For example, if you will create a policy that
relies on domain user authentication, ISA Server should belong to a
domain.

If the ISA Server computer is protecting the edge of your network, we
recommend that you install it in a separate forest (rather than in the
internal forest of your corporate network). ..."

Can you please elaborate, Jim?

> You can adapt the ISA deployment to that later.

Good point.  On the same token, I want to focus on doing it right the
first time.

Much appreciated,
