2 sites 2 domain controllers and DSL connectivity, How to do it.



Currently: (site A)
1 main site
DSL connectivity
SonicWall Firewall (SOHO)
One domain
One domain Controller
domain.org
15 users

Setting 2nd site: (site B)
A new main Site
DSL connectivity
No Firewall
One Domain Controller
50 users

Site B will start off with DSL for 2-3 months until they get Metro
Ethernet connected to it.

How do I separate this domain in 2 separate sites while maintaining
authentication in both.

Should I create 2 domains? (I rather not)

Can I just take one domain over there and have it without replication
until the Ethernet is up and running?

Is it Necessary for me to have a VPN for replication? (I will not start
with a vpn)
