MS CRM 2011 Beta - Error adding user on On-Premise

You may get the following error when trying to add a user to an on-premise organisaion in MS CRM 2011 Beta.


Errors:
1. You do not have the necessary permissions to change the domain logon name for this user. The following user was not added: ....
2. An error has occurred


As of now the resolution is an IISRESET on the CRM Server.
1.) Open the CMD window (Run as Administrator) on the CRM Server
2.) type iisreset, then Enter.


Hope this helps.
