    Hi All
    We are opening a branch office and have ordered a 2MB leased line at each
    site and an MPLPS network that links them together.
    The leased line suppliers think that I do not need to set up seperate
    'sites', and that DNS, dhcp and authentication can be done over the WAN link
    without too much bandwidth being hogged.
    I also use an IT support company, and they tell me using WAN link for dns,
    dhcp and authentication would have an adverse effect on the WAN link speed -
    and recommend against it. They think I should set up two sites, and so have
    inter-site replication which is a more efficient use of bandwidth.
    Given out computer needs are failry light and standard (MS Office, Email, an
    ERP which would only be accessed from one site only, and some file storage) I
    am not sure.
    I realise this is quite an open ended question too, but has anyone any
    opinions on this please
    TIA

  2. Use the AD Sites Object.

    Anything slower than a fully syncronous (same speed both ways) 10mbps link
    is considered "slow". Some might argure that anything less than 100mbps is
    "slow".

    It is not all about bandwidth either it is about the link being over the
    internet which will inevitablly at some point "go down". You want the LANs
    to still be survivable in such a case. So have a local DC with DNS, DHCP &
    WINS running at the local Site. This will keep local logins and local
    authentication functioning if the links drops out.

  3. Hello Lewej,

    Use Active Directory sites and on any site a DC/DNS/DHCP/GC server, so your
    users can also work if the WAN link is down for whatever reason.
