Hi Soonhat, Firebird 1.5 is very very old I suggest that you move to something newer if possible. The default password on Windows is actually masterke Do you need to use BDE. BDE is deprecated and older than FB1.5 by many years. There are tools to manage FB that come with the download. There are also many tools that you can download that vary from free, open to commercial. I wouldn't be without DB Workbench
Goodluck Mick
