We connect a client to the server just fine.  We can see the redirected folders from within Windows and can explore the folder but they appear empty in Windows (although there are files in them) and we can not place files in them from windows.  We have tried folders at the root level of the drive, in the logged in users home directory, and in Users/Shared all with the same result.  Any ideas?

Hi,

Can you access the files inside that folder from other client system?
Does this happens with single user account or for all users?
Do you receive any useful log for this case?

You can collect log from below path.
Microsoft Remote Desktop>About Microsoft Remote Desktop>Send log via email
Hope it helps!

Thanks.

Yes we can access these files from other clients both via afb and smb.  It happens with all accounts and here are the only 2 log entries I see:

Mar 30 08:36:41 George-Orwell-2.local Microsoft Remote Desktop[32661]: modalSession has been exited prematurely - check for a reentrant call to endModalSession:

Hi,

Drive redirection is supported for remote resources, so that you can save files created with a remote application locally to your Mac. The redirected folder is always your home directory displayed as a network drive in the remote session.
In order to use this feature, the administrator needs to set the appropriate settings on the server.

So from above words you need to check whether there is properly setting on server side. Please check related policy setting. User Configuration\Policies\Windows Settings\Folder Redirection

You can get more information over here.

Hope it helps!

Thanks.
