Hi,

If the DC is failed and never comming back up again, you have manually remove if from Active Directory.

Use this guide (Just the same as MS KB, but a bit easier to understand).

If you are going to reinstall a the computer, choose another name for the DC (ie, not the same host name as you used before).

Good luck ;-)

Is the Server in question that you need to remove, does this hold any FSMO Roles? If so you need to seize the Roles as you will not be able to transfer them. You can use the Ntdsutil.exe from the command prompt to seize the Roles, refer to link below.

Also, make sure that one of the other Domain Controllers is a Global Catalog Server.

You can follow this link below to remove the dead Domain Controller.
