How to fix Verification of prerequisites for Domain Controller promotion failed.

Verification of prerequisites for Domain Controller promotion failed. The local Administrator account becomes the domain Administrator account when you create a new domain. The new domain cannot be created because the local Administrator account password does not meet requirements.

Currently, the local Administrator password is blank, which might lead to security issues. We recommend that you press Ctrl+Alt+Delete, use the net user command-line tool, or use Local Users and Groups to set a strong password for the local Administrator account before you create the new domain.
