UPD template is not created after enabling User Profile Disks feature
UPD share is being created by RD Session Host Agent which is being modified. You should add Computer Account of the RD Session Host to the Local Administrators group on the File share server.
For example, if you are enabling UPD in the properties of the RDS host rds1.ras.com and specifying the share located on the FS host fs1.ras.com, following should be done:
1. On the FS host fs1.ras.com open compmgmt.msc applet and navigate to Local Users and Groups > Groups > right-click Administrators group > Properties > and add rds1 host in the list:
2. Disable and enable UPD in the RAS Console
