Question : adding new site and subnet to network

I have a single site domain with 60 users and are adding a remote office (5-10 users).  I'm also running low on IP addresses and need to add subnet to dhcp (192.168.1.x).  The plan now is to add a server in the new location with file, print, ad, dhcp (192.168.2.x) and put that server in a new site physically and within AD connected with vpn.

current setup is 2003 sbs, 2008 server, exchange 2007.  we will be moving to exchange 2010 in a few months time.  

What's the easiest way to achieve (new to multi-site)?

Answer : adding new site and subnet to network

It sounds like you pretty much know what you have to do...

Set up a secondary site with VPN routers connecting the two. Make the new site 192.168.2.0/24 and add your Domain controller with DHCP/DNS/AD services for the new subnet. Make sure to add the new subnet in sites/services.
