RDP bug
I have computer without monitor. I use it only for bruteforce:
OS: Windows 7 SP1 64bit
Hashcat: oclHashcat-plus-0.12
GFX: AMD Radeon HD 6990

When I'm attempting to use RDP to the machine that is running hashcat I'm getting this error:

RDP uses a virtual display driver rather than fglrx, and that is likely why ADL is failing. It's not a problem per se, you just won't see temps or get fan control.

The biggest question is why are you using Windows? Why not use Linux if you have a headless server dedicated to brute force?
Problem with the AMD driver.
Use --gpu-temp-disable to be able to run anyway.
