Cannot RDP in WAC when account is a member of Protected Users

Guyver1 Did you ever figure this out?  I don't use Server Manager or WAC, but I have discovered that the MS RD app (little red circle with GT and LT symbols) will NOT allow me to connect to anything remotely when I'm in the Protected Users group.  However, the original RDC app (aka MSTSC.EXE) will allow me to connect remotely, but only when I'm in the office on the local subnet.  If I connect at home, through our Sonicwall VPN, neither the RD nor the RDC app will allow me to connect.
