VirtualChannelInit застревает

Я разрабатываю приложение виртуального канала RDP. Я зарегистрировал клиентскую DLL в реестре и пытаюсь понять, что клиентская DLL загружена.
Но я застреваю при звонке pVirtualChannelInit от pEntryPoints,
Он просто не возвращает никакого результата, отладчик переходит к дизассемблированному коду этой функции. Но если не останавливаться на этом вызове, VirtualChannelEntry звонили во второй раз (почему?).

Если я использую отладчик для mstsc.exe.
Через некоторое время после первого звонка в консоли я вижу это:
First-chance exception at 0x00000004 in mstsc.exe: 0xC0000005: an access violation in the performance at 0x00000004. // переведено с помощью Google
И после второго звонка, когда на экране появляется сессия rdp:

Указатели в pEntryPoints всегда:

pVirtualChannelInit - 0x00000004
pVirtualChannelOpen - 0x0000ffff
pVirtualChannelClose - 0x000000b8
pVirtualChannelWrite - 0x00000000 (Why 0?)
