Try changing your code to:

cn.Server := '';
cn.Protocol := cpTCP_IP; {If it's not already assigned in design-time}
cn.Path := 'C:\Program Files\Firebird\Bin\TMS.GDB';
cn.Username := 'tarak';
cn.Password := 'test';

It's just that the property DatabaseName is automatically formed by
combining the properties Server and Path.
