The SMS Mirror driver is the root cause of the problem, with help from a dated video driver, the SMS Remote Control application (Wuser32.exe), and an unsupported operating system (Windows 2000).
So what does the SMS Mirror Driver do?:
Video acceleration significantly speeds up your Remote Control sessions clients. For video acceleration on clients running Windows 2000 or later, SMS uses a Mirror driver. The Mirror driver can simultaneously display the same output to several video devices and has no dependencies on the client’s video driver.
