  1. Need help

    iam running a mixed mode of W2k3 with few NT BDC which are
    across the Wan link ,so when users authenticate they
    should authenticate to local BDC and not W2k3 DC across
    WAN Link so any idea how to force local authentication.

    Pls reply asap

    By default Win2K and WinXP machines latch on to Win2000+
    DCs and bypass the NT BDCs (once they find the new DCs.)

    Upgrade at least one DC per site to Win2000+.

  3. Hi Sanjeev,

    Thanks for your posting here.

    Herb's suggestion is right. As for Windows 2000/XP clients, it will use
    Windows 2000/2003 DC for authentication after DC upgrade. Please refer to
    the following articles for more information.

    Windows 2000-Based Clients Connect Only to the Domain Controller That;en-us;284937

    How to Prevent Overloading on the First Domain Controller During Domain

    This can be worked around by using the NT4Emulator registry placed on the
    Windows NT 4.0 PDC before it is upgraded to Windows 2003.

    As for your scenario, I recommend that you upgrade the BDC in remote site
    to Windows 2003/2000 DC. If you upgrade the NT BDC to Windows 2003 DC, the
    Windows 2000/XP clients in remote site will contact the DC locally.

    Have a nice day!
