Logon failed.

Cause

This error probably means that Crystal Reports is trying and failing to log into the MySQL server using an ODBC connection.

Solution

The first thing to do is check the ODBC connection on the computer with the error, and make sure these settings are properly configured:

  • Host
  • Username
  • Port

If ITrack can connect, but Crystal Reports (through the ODBC connection) can not, the problem almost always has to do with the settings for the ODBC connection.

It is also possible that some sort of software firewall could be blocking ODBC, but not ITrack itself.
