iNTERBASE OPENSOURCE Problem : Interbase Server is currently not installed

Hi,

I got a problem with Interbase 6 Opensource installation.
I installed IB6 on NT4SP6 and win 2000 as administrator. With that accopunt
I can access the database via delphi without any problems.
But as a normal user I cannot access the database with delphi. The interbase
manager always tell me that the IB6 Server is currently not installed. The
root directory is shown as unknown. The strange thing is that in the task
list ibserver and ibguard is running and I can manually log into the
database with ibconsole.

Does anybody know that kind of problem. Maybe ikt is a configuration error.
I would appreciate any help.

Thanks in advance

Dirk Bernhard
