Hi again, I have unsuccessfully tried the delayed approach and it is not working, each attempt produced the "Invalid descriptor" error. As David said, maybe the MS implementation is doing its own assertions but that would be unfortunate. When I will have more time I'll try running the code with a kernel debugger attached.
In the meantime, I am considering a workaround using both SVC and DVC. The idea is to use the SVC while the user has not yet authenticated and then to switch to DVC. Once the client is authenticated, I need the SVC to be unusable on both sides. Is this possible using the API ? Regards, Thomas Calderon.
