[Solved] Verification of prerequisites for Domain Controller promotion failed.

You may get the following error while promoting the machine to a domain controller. Below is the complete error with its solution.

The Error Message:

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, a password is not required for the local Administrator account. We recommend that you use the net user command-line tool with the /passwordreq:yes option to require a password for this account before you create the new domain; otherwise, a password will not be required for the domain Administrator account.

Solution:

Execute the following command on Powershell.

net user Administrator /passwordreq:yes

  1. In case above do not work.

    Do following instead:

    You need to set a password for Administrator. Go to Computer Managenment -> Local Users and Groups and click Administrator user and click Set Password and rerun the prerequisite check.

  2. I just ran into this too – in fact, there may be another reason. Local Security Policy (secpol.msc): Look at Account Policy / Password Policy / Minimum Password Length. If this is Zero, it means a password is not required. Even after setting this to a value, it is probably good to enter the “net user Administrator /passwordreq:yes” command, and to make sure the Administrator account has a password that meets the secpol.msc password requirements, then try again. 🙂
