Best AD/DNS 2003 design practices for multiple international sites?

Discussion in 'Active Directory' started by Robert Gordon, Aug 25, 2007.

  1. Can anyone offer a best practices recommendation for laying out AD 2003
    with a headcount layout similar to the following?

    US West Coast HQ: 100 - 400 users in a single location (10 MB Internet)
    Japan: 10 - 20 users (5 MB Internet)
    London: 20 - 30 users (10 MB Internet)

    All three sites will be connected via star topology IPSec VPNs.

    I am trying to design the sites so that should a link break, apart from
    temporarily losing direct connectivity to the main HQ office's Exchange
    Server, each site would be able to continue functioning as an
    independent unit by having it's own DC in place.

    Would it make sense to lay out AD as follows: for US for Japan office for UK office

    Or would just keeping the entire company on a single flat AD layout do just as well?

  2. Hello,

    i would put it as a single domain to keep it simple. 10 users doesn't
    justify a domain, neither 30.

    The real issue is about exchange..Is outlook's cached mode enough ?
    Hope so, else it would cost much more money.

  3. Yes, plus the fact that a large number of these remote users would have
    Windows Mobile devices, so as long as the main HQ Exchange server was
    online, they would still have a way to send/receive emails (in
    additional to webmail via any local wireless cafe).

    It's not star, it's triangle.
    Separate domains are for security policy and replication (entire directory
    vs GC) partitioning. You don't seem to have a requirement that justifies
    extra domains.

  5. Would it then make sense just to place each remote location under it's
    own site within the domain?
