Language: Delphi7
Firebird: 1.5

I was having trouble with a third party component (dbisam) with a Data
Execution Protection problem at several customers.

See the following for DEP description:

I upgraded a Windows Server 2003 to SP1 in order to duplicate the
problem but now that it's been upgraded, Firebird no longer works.
Firebird (via IBConsole) tells me that the Database is Invalid when I
try to connect.
