We have an ISAPI DLL running under MS IIS 4.0. When the DLL is referenced in a URL from MS IE 5 it works correctly.
When it is referenced in a URL from Netscape 4.7 the browser starts to download the DLL.
We have execute permission in IIS on the web root and EVERYONE all access on the DLL in NTFS. So its something different between MS and Netscape browsers.
