    I have a PDC and a BDC with Exchange 2003 on the BDC and both servers
    running Windows 2003 Server - Enterprise Edition.

    I decided to upgrade with SP1 on the PCD yesterday and on the reboot the
    server won't come up. On Safe Mode the last file being loaded is "acpi".
    Anyway that is a whole other problem.

    Now I have the BDC w/ Exchange 2003, but non of the Users can login from any
    of the workstations. I know and see the active directory info on the BDC.

    Can someone tell me what is wrong? Do I need to change something somewhere
    that will tell the workstations to authenticate to the BDC??? I have tried
    "BDC\UserID" instead of "PDC\UserID" ...with no luck.

    I appreciate any input.

  2. Hi,

    There is no such thing as PDC and BDC since Windows 2000. All domain
    controllers are equal (multimaster domain).

    - Is your second domain controller also a global catalog (GC)? If not then
    logons won't work.
    - Is your second domain controller also a DNS server? If not is there any
    other Active Directory server still working on your network? If not --
    logons won't work. If yes -- do your clients know about this second DNS
    server (do they have it entered under TCP/IP settings). Clients use DNS
    server to locate domain controllers and global catalogs. If DNS is not up
    and running they can't locate them...

    How to create or move a global catalog in Windows Server 2003, Windows 2000,
    or Small Business Server 2000

    Mike - although your comments re DNS and Global Catalog were remotely helpful your claim that "there is no such thing as PDC and BDC since Windows 2000" will not help people who can clearly see they have a PDC and BDC(s) in a 2003 only environment and are experiecing the problem decribed in this thread!

    Thanks for nothing. If anybody has any ideas of how to solve this problem WITHOUT claiming that certain aspects don't exist that would be ace!
