Rdesktop Internal licensing error
If you get the following error message when running rdesktop to connect to a Remote Desktop to a Windows server
Autoselected keyboard map en-us disconnect: Internal licensing error.
Then try running
rm ~/.rdesktop/licence* && rdesktop windowsremote.engineering.iastate.edu
rm ~/.rdesktop/licence* && rdesktop <windows server name>
There is a license file that gets created when using rdesktop. At some point Microsoft changed their remote desktop authentication, so you need to remove the license file each time before starting rdesktop.
