2008 branch with sbs2003 office - help

I will be installing a 2008 Server into a Branch where the main office has a
SBS2003 Standard edition server R2.  I have already setup the IPSec VPN
Tunnel between branch and office and a PC at the Branch can now ping the
office network PC's due to the SBSserver being installed as a single network
card install.... and this now works absolutely fine....so all I need to do
now I believe is to add the 2008 server while at the office to the SBS2003
network as a Secondary domain controller using the ADPREP tool and then take
it off site to the Branch....This all sounds too easy......so please can
someone give me the full low down on what else is required.  What I am trying
to achieve is a seemless connection between sites to provide access to the
SBS2003 shares and exchange if possible, although no exchange is installed on
the Branch server.    Any help you can offer is much appreciated.
I have installed many SBSservers and Windows Servers but never yet gone
onto this step....so please help if you can.

Adprep upgrades the schema to (2008 v44, or 2008R2 v47) allowing for newer
OS versions of domain controllers. DCPROMO and adding the AD Directory
Services role enable the second server as a domain controller. These are
seperate processes.

I am not sure what you expect from the branch office domain controller you
are proposing. If what your object is to provide seemeless connection
between the sites (SBS2003 shares and Exchange) the remote DC is not really
going to do all that much for you. DC's provide authentication and in AD,
DNS.  - Without connectivity to the SBS site, remote users will not be able to
authentication, resolve names (DNS), access SBS shares, or access Exchange.
Adding a remote AD Domain Controller only provides remote users with the
first two, not the last two.

SBS2003 Office with 2008 Branch

Hi Thanks for the reply--- What I am trying to achieve is a seemless connection to the main offices shares that are available on the SBSserver.  I already have the VPN Tunnel via router to router IPSec but i am unable to access the SBS2003 shares from the PC at the branch and was advised that I would need to install a secondary server acting as a secondary DC to obtain access.  I do not want to use a PPTP VPN connection.....I want it to be a true WAN.  I am open to suggestions......but from what I have read so far this seems to be the only option.
