Lumia 920 driver problem on Windows Server 2012 R2

[Stevo Zilik]

Hi,

I cannot see my Lumia 920 in devices on windows server 2012 r2 when connected via usb.

In Device Manager, there is a warning in 'Other devices':

Nokia Lumia 920 (RM-821)
The drivers for this device are not installed. (Code 28)
There are no compatible drivers for this device.

Any ideas how to fix this?

Thanks,
Stevo
