Lost: password. Answers to name of "Administrator"...
… last seen being used by the person we paid to build our database. They’ve now gone away, and they don’t appear to know what it is any more. And, of course, nobody seems to have handed it over. This has prevented the database from being updated for some time. It also means that I can’t access the relevant bits of the DB server configuration to enable the JDBC interface that I need to use to talk to it.
Fortunately, it seems that the password/security implementation for FileMaker Pro is extremely poor, and that a $30 piece of Windows software can reset the password in a couple of seconds. Problem solved for all concerned.
