When you use the Configure Your Server Wizard to promote the first domain controller in a forest, the password for Directory Service Restore mode is set to a null value. This may allow a malicious user to log on to a domain controller without proper authorization. In addition, when the Directory Service Restore mode password is set, the password for Recovery Console is automatically synchronized with that password. Therefore, computers that are affected by this vulnerability have a blank password for both Directory Service Restore mode and Recovery Console.
Note that there are some significant restrictions to this vulnerability:
This problem affects only domain controllers. Computers that are not assigned as domain controllers do not have Directory Service Restore mode available.
The Configure Your Server tool can only create the first domain controller in a forest, so only that computer may be at risk. All subsequent domain controllers must be created by using the Dcpromo.exe tool, which is not affected by the vulnerability.
Domain controllers should be physically protected. There is no way to remotely exploit this vulnerability. If a computer has been properly physically secured, it is at minimal risk.
