  • What is the best way/best pratices to join 3 different domain?

    Hi all,

    I've a project on-hand which involved three different AD domains (Domain A, B & C) in different company as well. (The bad news is I don't have much AD experience)

    The client would like move all the sub-company into an new building. Therefore, they're plan to group/link up all the A,B&C domain together.

    What I'm thinking here is create two-way trust of among the three domains, so that it can communicate with each others. Is that possible?

    Please do share with me if you have any better suggestion.

    Thanks a lot!~

    Hi,

    The good news is that this could be achievable and the other good news is that you are on the right tracks with creating Trusts between these domains.
    A little more information is needed though regarding the existing domains.
    Such as, OS used in domain controllers, Domain and forest functional levels etc to better pinpoint you to the right solution.
    I do however think that for such a project, a bit of experience in AD could be the difference between meeting project targets in time.
    In the other hand, you will gain a lot of it when the project completes.

    I'd say start by using google for information like:

    How Domain and Forest Trusts Work - http://technet.microsoft.com/en-us/l...78(WS.10).aspx

    Creating Forest Trusts - http://technet.microsoft.com/en-us/l...10(WS.10).aspx

    Hope it helps
