Disabling the redirection of local resources
One of the neat things about users connecting to virtual sessions within an RDS environment, especially when connecting remotely, is local resource redirection. This feature enables users to have access to things that are local to where they are sitting, from inside their virtual session, such as the clipboard, so that copy and paste functions will work between the local computer and RDS session and drive redirection so that you can save documents back and forth between the local hard drive and the RDS session. One of the most common uses of resource redirection is printers so that users can print from inside their RDS session, which is sitting on a server in the corporate network, directly to a printer on the local network where they are connected. An example could be someone needing to print a work document on a home printer.
This redirection technology can be very helpful but is often not desirable from a security and policies standpoint...
