I have 18 small branch offices (less than 150 people/office) that currently
come thru the T1 to authenticate.
Total of 5,000 users coming thru the T1 for authentication.

Currently I have total of (3) Dc's on the main site. If I make the
PrimaryDNS and SecondaryDNS DC's in order to enable the ADI, that would be 5
DC's on the main site.

4 major branch offices have one DC/GC per site; about 800 users/machines on
remote branch offices.

As I said before, other small branch offices have less than 150
people/machines and I let them come thru the T1 since the T1 utilization is
really low and that has been working alright.
