My DC who was operations Master died, and cannot be revived.  Getting SAM error on remaining DC

My DC that was Op Master died, and now I am getting a crazy amount of SAM errors on my remaining DC, saying I will be unable to create new accounts.  I cannot change the operations master to the other machine because I cannot get it revived - so it says it's "offline" when I go to the AD Scema snap in.  I had AD running on both machines when th op master died,and the AD seemed to be replicating fine, in that if I made a new account on the op master it showed up in users and computers on the second DC, so I thought it wouldn't be a big deal.  I get an error saying that "the account identifier failed to initialize properly..."blah, blah and I think that this has to do with the operations master roles not being transfered.  I cannot add users and everything is messed up.  I am an AD lightweight, so go easy on me please...Can anyone help?

    Ensure you have the DNS Service set up on your new Domain Controller.

    Then here's how to force transfer the roles onto the new server:


    Then start typing this lot in (at any time ? shows the lists of available commands):

    connect to domain <your domain>
    connect to server <your server>
    quit <quits to FSMO Maintenance>
    seize PDC
    seize Domain naming Master
    seize RID Master
    seize Schema Master
    seize Infrastructure Master
    quit <quits the program>

    Confirm each of those is taken over correctly. It'll let you know after each one

    Make your server a Global Catalog (right click on NTDS Settings for the Server in Active Directory Sites and Services).

    Let me know if you run into any problems with that.

    I should have added this point.

    It's really really important that after Seizing those roles your Old Server **never** comes back onto the domain.

    If you recover the hardware it must be rebuilt.

    I assumed all roles were on the old server, obviously you won't need to seize roles if the server already runs them or another working server has it.

    Sorry for all the additional comments, think I need a coffee.

    Just to check - you only need to seize the roles that are no longer available, so be careful -

    Another way to locate a FSMO role holder.
    The following is th ms article that relates to Chris's post above:
    Using Ntdsutil.exe to seize or transfer FSMO roles to a domain controller;EN-US;255504

    Once you've successfully seized roles you will then need to remove your extinct dc from active directory:

    You may also need to look at establishing a new global catalog server if that was set on the old dc - will post on that if you need further instructions
