Posted on 2005-05-16

I Have Server 2003 and it was set up as  a Backup domain Controller.

The PDC no longer exists.

I need to remove it from the domain.

When I run PCPROMO it will not allow me to demote the server when "This server is the last domain controller in the domain" is checked  or unchecked.  When it is Checked it returns "Operation failed because:  This domain controller is not the last domain controller in the domain. "The Server is unwillingto process the request.""

When unchecked it says It can not contect the Doman Controller to process the request.

How can I remove the domain from this server?

Can anyone help?

    So do you have a PDC left in the domain?? Can you re-explain making things making things more clear?
    You say you had 2003 as a backup domain controller and the PDC no longer exists??

    If you need to Force a demotion you can use the command with the swtich

    dcpromo /force

    There is no PDC left in the domian. Yes 2003 was a backup domain controller.  The /force switch does not work.

    If you dont have the first PDC in the domain and you are trying to demote this one.
    Thats why you are getting these errors, for a domain to exist there must be at least one Domain controller!
    So you want to ditch the domain and have this as a stand alone machine.

    Windows Server 2003 domain controllers support forced demotion by default. Click Start, click Run, and then type the following command:

    dcpromo /forceremoval

    Click OK.
    At the Welcome to the Active Directory Installation Wizard page, click Next.
    At the Force the Removal of Active Directory page, click Next.
    In Administrator Password, type the password and confirmed password that you want to assign to the Administrator account of the local SAM database, and then click Next.
    In Summary, click Next.
    Perform a metadata cleanup for the demoted domain controller on a surviving domain controller in the forest.

    If you removed a domain from the forest by using the remove selected domain command in Ntdsutil, verify that all the domain controllers and the global catalog servers in the forest have completely removed all the objects and the references to the domain that you just removed before you promote a new domain into the same forest with the same domain name. Windows 2000 Service Pack 3 (SP3) and earlier global catalog servers are noticeably slower to remove objects and naming contexts than is Windows Server 2003.
