Re: Connection to posgresql database works under windows scripting host but not IIS/ASP

In that case...

Try logging in as the Anonymous Internet User and running the .vbs.

Check all your permissions and ownership and "run as user"'s. That means files,
directories, COM+ objects, --->REGISTRY ENTRIES<--- (use regedt32), your COM+
isolated applications in "Component Services", etc.

Also, do you have Crystal Reports installed on the box?
