Symptoms

Windows 7 and Windows Server 2008 R2 include the Remote Desktop Protocol (RDP) feature which provides a user with a graphical interface to a remote computer. When a User connects to a remote computer with RDP and attempts to load a graphics mirror driver on a remote system using this remote desktop protocol, the mirror driver may fail to install or start.

Cause

A specific flag needs to be written to the registry to enable correct function on the remote system.

Resolution

The mirror driver's INF file must include TSCompatible in the SotwareDeviceSettings section of the INF file, for example:

[mirror_SoftwareDeviceSettings]  
HKR,, TSCompatible, %REG_DWORD%, 1
