RDC 2.0 will not connect to Windows 2000 Server

  A client is having an issue where after upgrading to RDC 2.0 on OSX 10.5.5, they cannot connect to their Windows 2000 server.  "You were disconnected from the Windows-based computer because of problems during the licensing protocol" is the error received.  I have attached a picture of the exact error message.

They do have more than enough CALs.
We have tested the following:
RDC version 2.0 works fine on Mac OS X 10.4.11
RDC version 1.03 works everywhere.

So far we have tried changing the TS licensing methods, erased temporary licenses as suggested before(Global data 'trick'), rebooted the TS, and checked our firewalls.

Any advice will help.

Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Microsoft did a terrible job creating and releasing RDC 2.0 for Mac, for several reasons. The problem you're experiencing is just one of them - I too have seen issues with RDC 2.0 not working properly with Windows 2000 Server.

I suggest either downgrade to the previous version of Microsoft RDC, or better yet - I use CoRD, version .5 beta (there's a stable version .4x)
