Client Deployment Wizard (Windows non-Domain)

I recall that in earlier versions, you could use the deployment wizard to deploy to non-domain joined endpoints so long as you had a local administrator account that was common to all systems. This was helpful for deploying to our lab endpoints, which are not joined to a domain. This is no longer the case (using I’ve even tried using the tool on a stand alone system using just the local UserName, Computer\UserName, and .\UserName; all fail with access denied or invalid parameter. This is disappointing.
