We are assuming that you are running PowerShell with elevated privileges and with an account that has the rights to join computers to domain.

Use the Add-Computer cmdlet.

I’m also adding the computer account to a child OU called WKS and the verbose parameter to get detailed information during the process.

Add-Computer –DomainName frenchitguy.com –OUPath “OU=WKS, OU=IT, OU=FR, DC=Frenchitguy, DC=com” –Credential frenchitguy.com\administrator –passthru –verbose

Enter the password and click yes.

See the result

Restart the computer now with shutdown /r

Your computer is on the domain now

Cheers.
