AD Seperation


I have 1 Active Directory with 3 sites. My client want to seperate the 3 sites with one indepedant AD by site.

Do you know how to do that ?

I have 2 ideas :

=> Disconnect multisite VPN & recover FSMO rôles on each site on the site server.
=> Classic migration to a new domain (but I have to install a new domain server & it will be longer than my first idea).

Thanks for your advices

Your first idea is fine... Provided your client NEVER, EVER wants to re-unite the domains or form trusts between them.  Personally, I consider the first idea really bad and something that shouldn't be considered.  The correct way is to install separate domains.  Trusts will be possible if the client ever wants them.  Yes, it's more work, but it's a more professional solution.  

The big question I have is why separate the domains?  This is not generally a good idea.

Lee is correct.  I assume the client is trying to solve a problem by splitting the sites into domains.  What problem are you trying to solve for?  There are likely other, less drastic, alternatives.

You should require at least 2 DCs for each domain, meaning you would need 6 DCs, minimum, so they may have to purchase additional hardware to support the proposed site "split".  This becomes a management nightmare, for you, I assume.
