With Microsoft Remote Desktop, connect to the console by using the correct "/admin" or "/console" switches (mstsc.exe /admin or mstsc.exe /console) depending on the Remote Desktop Client (RDC) version being used. The Remote Desktop Client (RDC) 6.1 no longer uses the "/console" switch to connect to the session 0. The "/admin" switch (mstsc.exe /admin) should be used instead.
