  Unless your Active Directory domain is delegated and reachable from
the public DNS (fairly rare), you have to have DNS queries for your AD
domain hit your internal DNS servers.

  Can you put SRV records in DRIVERS\ETC\HOSTS?  If not, I don't think
that will work.  AD uses SRV records to find DCs and GCs.

  Why not?  DNS is *tiny* compared to most protocols.  One 512 byte
packet for the question, one for the answer.

  If you absolutely cannot accept DNS on the VPN, then you'll have to
put a nameserver at each remote site, and configure the nameserver to
forward queries for your AD domain to your internal DNS, while
allowing all other names to go straight to the public net.  This can
be done the MS-DNS that comes with with Win 2003 or later.  You could
also do it with ISC BIND on any old PC, provided you allow zone
transfers from the DC to BIND.
