As always, it helps to give as much detail as you can. We don't know which version of Windows you're using, so it would be difficult to give you step-by-step answers. And you certainly didn't tell us you're trying to connect to a remote database.Did you enable the MySQL service, and is it running?Do you have a firewall running, and is it configured to allow connections on the MySQL port?Is osTicket running on the same machine, or a different machine from the database? If different, is it on the same internal network? The questions could go on and on.Jack
