I have several WMS 2012 boxes with Atrust m300 zero clients. I am having an issue since upgrading from WMS 2011 that my zero clients displays don't sleep. The direct connected ps/2 stations display will sleep, but all other clients won't.

Per this technet article it sounds like I would need to enable the SessionIdleTimeout regkey to disconnect the idle sessions. I have enabled this key, but it does not appear to be doing anything on my multipoint server.
I guess my question is does anyone with USB attached zero clients have display sleep working in some fashion?
