Windows 2000 secondary DC died

Posted on 2006-04-18
Last Modified: 2010-04-13
The system is attempting to boot to a PXE complient nic only instead of the HD.  How do I demote this out of DC status without the OS?  What is the best course of action to take, if any to get this dc back online?  The HD appears in the Bios so it may be boot records

    If you don't have a backup of the machine, and you're not able to bring it back online any other way (ever!), you need to seize any FSMO roles the dead machine might have held to another DC, then you need to clean out the AD.

    Dell tells me the drives themselves went.  Can I just reformat the machine, call it the same name (after deleting from the computer list in AD), join it to the domain and dc promo it?  I do have backups of the data shares so I can put those back.  If I promote it, will the system react the same way and do I need to remote the previous DC attribute somehow?

    If you reinstall without restoring the system state, you first need to remove the old machine completely as described above; deleting the machine account is not enough! A reinstall will always create a new machine, same name or not.
    If you remove the dead machine first, then reinstall and dcpromo with the old name, there should be no problems.
