RDP on Mac Licensing Issues
We recently ran into an issue with connecting Mac’s to the Microsoft Terminal Server. The terminal server was installed with a temporary license while we tested it. Over Christmas break licenses were installed and the Windows and Linux machines had no trouble getting a license. Some (not most) of our Mac clients did not get an updated license. We would get the error:
You were disconnected from the windows-based computer because of problems during the licensing protocol
I was pointed in the general direction of a solution here. After deleting the contents of /users/Shared/Microsoft/RDC Crucial Server Information/ I still got the same error message. I went to a Mac that was working and copied the contents of said folder to the Mac that was not working. This fixed the problem.
(I also tried to reinstall Remote Desktop but still got the same error)
I’ve also come across this but found the solution – think like a Windows user. See http://twtwo.net/archives/10 for full details
Just use CoRD. Its much better.
None of this worked for me on two new 2008 servers. This link, however, solved it immediately by deleting the x509 keys (and server reboot). Nothing on the clients were necessary.

(note there is an error in the article. The actual registry path for the 509 is HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\CONTROL\Terminal Server\RCM)
The above works.. Once. Then you have to redelete again. I nuked the whole RCM key and rebooted, so far so good.
