I can speak for at least RDP Client 5x and up for windows, and Yes it is
encrypted at 128 bits as of windows 2000 sp1

Subject: TS/3389 risk on Internet


I have a peer that insists on allowing public access to his Domain
controller via TS/tcp 3389 over the internet.  I know there are some
documented cases of 'man-in-the-middle' attacks for this service but I was
hoping someone here could help me plead my case as to why this is a bad
idea.  Maybe you all disagree and regurlary allow this traffic.  It just
doesn't sit well with me.  Does anyone know if the login/password is sent
in
clear text for TS authentication?

Thanks in advance for any thoughts,
Nicole
