After Recompose "RunAs" no longer works

[cshenberger]

I have a couple of users who after a recompose of their view desktop the runas command no longer works and instead when trying to runas they get an error "The system cannot find the file specified".   It is the same couple of users after every recompose.   We have unassigned the users and assigned them to different machines and same issue after the next recompose.   We assigned to a new machine and didn't allow the profile to be copied and still same issue.

We had the same problem. For us it was caused by the GPO setting "Do not log users on with temporary profiles" : Computer Configuration\Policies\Admin. Templates\System\User Profiles

If this is enabled, try disabling it. When you "run as different user" windows creates a temp profile for that user. If the GPO configuration above is enabled, Windows can't create the temp profile and will display exactly the error you're seeing.
