After the Terminal Services mirror driver is disconnected from a Windows Server 2008-based or Windows Vista-based remote computer, you receive a Stop error on the remote computer: “Stop 0x0000007E SYSTEM_THREAD_EXCEPTION_NOT_HANDLED”
You use a Terminal Services mirror driver to access a Windows Vista-based or a Windows Server 2008-based remote computer. After you disconnect the mirror driver from the remote computer, the remote computer may crash. In this case, you receive the following error message on the remote computer:
Stop 0x0000007E (c0000005, Parameter2, Parameter3, Parameter4)
For example, assume that you use Live Mesh to access a Windows Vista-based remote computer. After you disconnect the Live Mesh remote session from the remote computer, the remote computer crashes, and you receive the Stop error message.
