title: Add user to local group on remote computer using different credentials
body: <p>I have credentials for the local "Administrator" user on every computer in my department. Sometimes, when I set the machines up for my colleagues, I forget to add my domain username in the administrators group (whoopsie!). It would be easy just setting up a remote desktop connection passing the Administrator user credential, but I'd like to do this "silently", so my question is: is there a way to pass those credentials by shell and then perform the usual operations for adding a user (mine, in this case) to the administrators group? </p>
  
  <p>I work with Windows machines in an Active Directory environment.</p>
  
  <p>Thanks.</p>
