If you're running RDS on a vSphere server with VMware Tools installed, you may have noticed the evergrowing presence of vmwaretray DMP files in the user profiles. These are crash dumps from the VMware Tray icon, which is ran during every session.

The reason for this crash dump is an error which is caused by lack of read access to a certain key in the Windows registry by your regular (domain) users.

This key is called HKEY_LOCAL_MACHINE\Software\VMWare. Inc.\VMWare Tools.

Set the permissions on that key to read access for the users logging on to the server, and your problem should go away.
