We just installed a new Server 2012 R2 RDS Farm:
2x Connection Broker Servers in HA mode (configured for Collection Redirection), 4x Session Hosts, 1x File Server dedicated to UPDs, no Gateway Server.
All Servers were updated with Windows Updates and RDS-specific hot-fixes before being put into production.
When the issue happens, some users get a temporary profile. We have to find the Session Host where the UPD is still mounted and detach it in Disk Management, then delete the profile .bak registry entries from HKLM\Software\Microsoft\WindowsNT\CurrentVersion\ProfileList
UPDs are configured to store all user settings on \\FileServer\Share. No excluded folders.
Problem occurs randomly: different days and times, random users
Any ideas what prevents the User Profile Disks from dismounting when the user logs off?
