Fixing the Local Administrator Account becomes the Domain Administrator Account

While creating a new Domain in my Lab, wasn’t able to promote the Domain Controller as the password for the Local Administrator is not required so the promotion will fail until the local administrator password is set to required.

Solution:

1. Open a Command Prompt as administrator.
2. Run the following command:

   net user Administrator <Password> /passwordreq:yes
   
   

3. Re-run the Prerequisites check and will now pass.
