Open a PowerShell window with administrator rights
Add-Computer -DomainName <DomainName> -Credential <DomainUser>
For example, the command would look something like this:
Add-Computer -DomainName cyber-ridge.local -Credential cyber-ridge\Administrator
After the command runs, you will need to type the user’s password and then restart the machine to complete the process. Since you have the PowerShell window open, use the Restart-Computer cmdlet to do so immediately.
