[X4U] rdp remote desktop server for 10.4 Tiger

[Jerry K]

I have need to remote control a Mac OS X 10.4 system from a non-Apple 
client.

I am currently doing this using the VNC protocol.  I have tried a couple 
  of different servers and VNC clients, and I have found VNC too slow. 
Yes, I have tried several tricks to address this, such as solid color 
back grounds, reducing colors, etc.

In discussing this with a non-Mac people, it has been suggested to me 
that the ms rdp Remote Desktop Protocol, is more efficient, and that if 
this option is available, they would expect that I would have much 
better performance.

Does such a thing exist? A Yahoo search turns up many RDP based clients, 
but I don't see any Remote Desktop servers for the Mac?

TIA,

Jerry
