Thanks for your posting and thanks for SuperGumby's input.
According to your description, I understand that you would like to install
a 2nd Server as Additional DC in the SBS 2003 network for fault-tolerate,
when the SBS Server goes down. If I have misunderstood the problem, please
do not hesitate to let me know.
Yes, we can install a 2nd Server as Additional DC in the SBS 2003 network,
which provides fault tolerance for user authentication and can improve the
availability and reliability of network services as well.
Generally, there is no much difference between the SBS 2003 server and
standard 2003 server to setup additional DC. Please refer the following
articles on deploying additional DC:

Small Business Server Network

| Hi, i did some searches on BDCs but cant' find anything specific to my
| situation so here goes.
| We have a SBS in our main office that our 3 branchoffices connet to via
| VPn lines. These are smaller offices, 1, 3, and 6 people respectivley. We
| consolidating 2 offices into 1, so we'll have 9 people in one office now,
| i'm thinking that i wanted to get a BDC running in that office.
| I'm looking for best practices advice. As of now i have users' My
| linked to their Z:\ which is on the SBS - so for the people in this
| i'd like to redirect that to the server that would be local to them. Also
| provide fault tolerence for printing and dns if the main office were to
| down. This would also help load balance.
| Now i'm wondering what the limit of doing this is? As of now if the line
| goes down they lose email - could exchange be replicated across this too?
| Just trying to keep as much traffic local as posssible.
| Any ideas, tips, experiences, do's and don'ts are apprecaited.
