RDP virtual channel in kernal driver

Hi,

In the msdn link for remote service virtual channel, it is given as "To use virtual channels, you must provide the server and client modules of a virtual channels application. The server module can be a user-mode application or a kernel-mode driver. The client module must be a DLL.".

But when I tried to use wts virtual channel apis in my vitrual audio driver , the driver was not installing properly. If I remove those codes for wts virtual channel from kernal driver the driver is installing properly.

Can anyone suggest the reason for this problem.

Thanks a lot.
