Hello!, Thank to JPD I was able to resolve the last problem the same night I posted my request for Help. Incredible! But nothing works endlessly on a computer without making trouble. So I came across the next thing i cannot fix on my own. The bd.cgi script does not find the default.cfg file. It say it's not in the directory http://artus/test/dbman but it really is. I can call it! Maybe the following error message can help someone to find a solution:

Error Message : Error loading required libraries.
Check that they exist, permissions are set correctly and that they compile.
Reason: Can't locate default.cfg in @INC (@INC contains: http://artus/test/dbman C:\Perl\lib C:\Perl\site\lib .) at C:\InetPub\wwwroot\test\dbman\db.pl line 51.

Script Location : C:\InetPub\wwwroot\test\dbman\db.pl
Perl Version : 5.00503
Setup File : default.cfg
TIA Klaus

In my experience, you need to use this,
in db.cgi set:

$db_script_path = "C:/InetPub/wwwroot/test/dbman";

Notice the forward slashes, not backslashes.

Katana Man is right, that's it! Thanks.
