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.

   

 

 

Adding A User/Group As A Local Administrator On A Domain Controller

Was recently patching my HomeLab environment when i realised i hadnt installed the SCCM Client onto my Domain Controllers.
One of the pre-reqs to install the SCCM Client is that the Client Push service account needs to be a local administrator on the server. As a Domain Controller doesnt have Local Users and Groups option under Computer Management, we need to add the service account via command line.

Run Command Prompt as an administrator and run the following command to add a service account called svc_SCCM_CP as a local administrator:
net localgroup Administrators /add TEST\svc_sccm_cp

If done correctly, you should get the message:
The command completed successfully.

Now i can install the SCCM Client without issues.
