vb dll works in IIS4, but not in IIS5 from ASP

[jlgdeveloper]

I have an image manipulating dll which works in IIS4 in an
asp page, but not in IIS5 in an asp page. It does work in
both environments when called within a vb app. I have
confirmed this behaviour on two separate win2k terminal
servers. The image dll creates thumbnails from jpeg's, and
manipulates tiff images. Since it works from within vb, it
is IIS, not the windows platform. The dll specific error
message indicates that the image data is not found, and
the Victor Image Library error indicates that the filename
is not found. Since I have it working on an IIS4 asp page,
and am not providing erroneous path info, I know this is
not true.

Any Ideas?
