Hi Aiden,
Did not mean to double-post... just re-visiting our 2012 RDS setup, and was hoping to be able to tunnel directly from the MS TS Client - without a tailored .rdp.
I am not able to do this, and a totally forgot the answer above, wich explains it.
SRY! I will go away now :-)
Best regards
Bjarke Emborg Kragelund
