Remote Desktop
Remote Desktop appears to be broken with all GPU versions of HashCat. The program runs fine until you login via remote desktop. When you login with remote desktop the program stops with the message NVAPI_NVIDIA_DEVICE_NOT_FOUND. When you close the remote desktop, it continues working correctly.

Seems odd that it would re enumerate hardware when logging in remotely.
u cant run oclhashcat via rpd
but you can with vnc
Exactly atom. I've been using mine with vnc and it works just fine. I would rather use vnc over remote desktop anyday.
