I'm looking for a good RDP client for Windows. The built-in one for WinXP doesn't do sound and puts black padding around the window for some reason.

Something like rdesktop would be perfect. I've tried getting it to run on windows, but I've run into problems. Even though I had XminG running as an xserver, it said it couldn't connect to the local display. Eventually I installed x/cygwin and compiled rdesktop myself, and that ended up working, but the sound still didn't work.

Is there any good rdesktop-like client for windows, or a stand-alone version that wouldn't require installing x/cygwin and compiling just to work?
