Warning! Terminating an account will completely erase all the information stored for it on the server. Make sure you have a backup that you can restore it from if needed before proceeding with this operation!

To terminate an account on your dedicated server first you need to login to WHM with your root password.

Once you do that, select the Terminate an Account link from the left menu. Then select the account either by its username or domain and click on the Terminate button.
