Database access failed : Host 'computer.domain.com' is not allowed to connect to this MySQL server

Error:
Database access failed : Host 'computername.domain.com' is not allowed to connect to this MySQL server

Solution:
When installing MySQL, make sure not to select the "Enable root access from remote machines" option.
Use 127.0.0.1 in the settings.php $DBSERVER value instead of the server IP address.
Example: Globals::$DBSERVER='127.0.0.1';
