I have a server 2008 r2 at one location and I am going to have a SBS 2011 at another location only running exchange (mail server).  What would be the best and right way, to join it to the 2008 domain or create its own domain and how.  I have a VPN running between the offices.

    Whoever sold you on SBS should have explained the product to you.

    You cannot join SBS, once setup, to an existing domain.  SBS MUST be the FSMO master DC in a domain.  You can migrate your existing domain to the SBS server, but you cannot make it simply an additional server in your existing domain (not even sure the options exist to allow you to, but if they do, it would only appear to work for a few weeks - after a grace period, the SBS server would start shutting itself down because you would be violating licensing.

    You also cannot have trusts between the two domains (SBS doesn't permit trusts since 99.9% of small businesses don't need them).

    At this point, if you called me in as a consultant to implement the best solution possible given the scenario you've described, I would wipe out the existing SBS server and reload it, migrating the existing domain onto it.  Once that was done, I'd leave the existing server as a DC (just not the FSMO master DC) and proceed from there.

    It's a brand new box, didn't take it out and configure yet.  So you telling me I should make the abs the main dc controller and join the 2008 server to the sbs as a secondary or a member. I want to utilize the exchange server built in the sbs.
