We have a Server 2012 R1 RDS / Terminal Server Farm:
Server1 = RD Licensing
Server2 = RD Session Host
Server3 = RD Session Host
Server4 = RD Session Host, Web Access, Connection Broker, Gateway and hosts the User Profile Disks.
We have a recurring issue where a user gets a temporary profile, no matter which Session Host he logs into. We found that the UPD is still attached in Disk Manager. When we delete the temp profiles out of the Registry, and detatch the VHD - the user can login and get his normal profile.
What is causing the UPD to stay attched?
