Its a bug in the 2.1.1 client and you need to get 2.1.2 to fix it; but, MS is not making it available.

I will able to resolve this issue by deleting reg entries and reinstalling the TS license.

1.      Make sure that the terminal server registry has been successfully backed up.
2.      Start Registry Editor.
3.      Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\RCM
4.      On the Registry menu, click Export Registry File.
5.      Type exported- Certificate in the File name box, and then click Save.

NOTE: If you have to restore this registry subkey in the future, double-click the Exported-parameters.reg file that you saved in this step.
6.      Right-click each of the following values, click Delete, and then click Yes to confirm the deletion:

X509 Certificate
X509 Certificate ID
X509 Certificate2
7.      Quit Registry Editor, and then restart the server.
8.      Reactivate the Terminal Services Licensing server by using the online method in the Licensing Wizard.
9.      Choose Reason for reactivation: The license server certificate has become corrupted.
