    it is not that easy...and the reason is the limitation of exchange and active directory.....
    so u will either do it manually....exporting and importing contacts and users from domain and importing it in to another(ur problem is a bit more complicated since u have to maintain a sync between three domains)....
    or a third party tool....something like MS MIIS...or i think quest software may also have one....
    u can also take a look at this one

    or this

    I know MIIS can do it for me, but it's a hard jub that try to learn and install & config it!

    and about Microsoft Exchange Server Inter-Organization Replication (your 3rd link) i try to use it and work on it about 8 houres but don't find any method for update GAL, it's only can update public folders and busy status. i think it's the simplest  way to do it.

    and in other hand if you can show me the way to update GAL manually let me know.

    Abulhallaj unfortunately i cant.....
    Inter-organization tool can be used to update GAL if u export all ur GAL in to a public folder (that is the trick)...

    there is a simpler method(if u have VPN between the sites) an outlook client
    (in ur profile) add a NEW DIRECTORY (internet directory service=LDAP) and
    point it to the DC in another domain(in ur case u should add two LDAP service since u have two other forests)...
    now when u open ur address book and click on the name u have given to the
    connection u will be able to see all the entries in the GAL.....
    this a much better and simpler method but as i said u need site -to-site VPN connection and u must configure each client individually or through a script....

    Thanks the secound method (Inernet Directory Service) is very usefull but it load the every time you need to use. So after all of this i Decided to use MIIS becuse we have Live Communication Server in our organization and it's need to join that toghather.

    Thnaks for your helP.
