ISAPI dll not running on Windows server 2003

I use a product - Magic - wich acts as a Web server.
The setup process works fine on a Windows 2000 server.
And it does not on a Windows 2003 server.
So I have 2 similar installations, one is working fine (2000), the other does not.
Going further to identify the problem, all tells me that the mgrqispi94.dll is not 'waked up' by an URL as http://myserver/Magic94Scripts/mgrqispi94.dll?Param1&Param2
I receive a 404 error...
The logical rep /Magic94Scripts/ is of course well defined, (scripts and executables) and has the same configuration than on windows 2000.
I it is a problem of permission settings, how can I so ?
the rep security is set to 'Anonymous connexion', using the 'Internet user' defined elsewhere.

Thanks for help.

Did you define a Web Service Extension in the IIS Manager?

Cheers
Ken
