I am using software from 2X to publish apps via RDS. I have enabled Drive Redirection so remote users can save files to their own local drives, but I want to disable remote users' access to server's drive. How shall I do this? Running Win Server 2008 R2. Thanks
As long as the users aren't given excessive rights to the server computer they're going to have exceedingly limited access to write on the server computer-- basically to the user profile and subfolders there. If you've giving them more rights then you're going to be fighting a losing battle.
Attempting to remove the users' ability to write to their profile directories is going to end in heartburn for you, likely with applications not functioning properly.
The built-in OS filesystem permissions are going to take care of you and prevent users from blowing-up the server computer. Aside from that, it sounds like a management problem and not a technical problem-- users should save where they're told to.
By all means, go ahead and use something "cosmetic" like the Group Policy setting suggested by Greg because it might make things a bit "cleaner", but don't grant users excessive rights irrespective of the "visibility" of the drive letters.
It is done the same way you would with a workstation. Use the following group policies:
"Hide these specified drives in My Computer"
"Prevent access to drives from My Computer"
