Users can't log in to our terminal server (Server 2008) from Mac using RDC 2.1. After typing in the server name, the client asks the user to login. The user fills in their username, password and domain but receives and error stating "The credentials that were used to connect to [server_name} are incorrect".
Any user, including myself who am a Domain Admin, get this error. When I log in using the domain's Administrator account, however, I can log in just fine.
None of this occurs when trying to login from a Windows client. The Mac I tested on is running OS X 10.5.8. Any help would be greatly appreciated. Thanks.
