We installed a complete new server 2016 environment with 5 terminal servers in a farm. We also use User Profile Disks for the profiles.
When the domain administrator is logged on to any terminal server and the terminal server gets started, we get after the logon of the domain administrator this message:
We can't sign into your account
... and the administrator gets a temporarily profile.
After logoff / logon the message isn't shown and the regular profile is loaded.
- We use the console logon for the rdp connection
- There is only one administrator logged on at one time
- The eventlog doesn't show any conspicuity.
From a comment: A similar error is described here: technet group. The cause in this case are DVDROM drives, which are connected to the location 1 on on the scsi-controller.
In my case the DVDROM drives are connected to SATA. For testing I removed the drives but the error still behaves.
BUT: This may be an hint, that also in my case the user profile disks couldn't be properly connected.
