I have a software development machine that will be accessed remotely via RDP, it is a virtual machine running as a guest in Hyper-V.
A hardware firewall is in place to prevent internet access or files to be transferred off the subnet.
Is it possible to restrict the file transfer and other mechanisms of copying data?
I'm running Windows 2008 R2 enterprise and open to all ideas including 3rd party software.
You can block port 3389 and/or go into group policy editor choose computer configuration then administrative templates, windows components, terminal services, then client-server data redirection and set 'do not allow drive redirection' to enabled.
For the record, you can actually copy and paste actual files to and from the terminal session and in between terminal sessions on this server version.
I'm not sure to got what you want to do but if you want to prevent users to move your documents and open them in other systems so you can restrict your files by Microsoft RMS. So they could not open these files anywhere else of your domain.
