I saw your fix earlier, but I missed the crucial sentence: "Also, it completely breaks authentication when the user uses IE5.0 when trying to log into a secure area of the server. These Custom Error handlers are enabled by default." Duh. It could be a good idea to putting this up as a HOWTO on zope.org under the title "How to fix HTTP error messages and authentication with IIS 4". Thanks.

I gotta ask, because I certainly haven't. I could not find any information on this on the list, either.

I turned off Challenge/Response and Basic Authentication and all I got was this lousy message when accessing a protected Zope resource:

HTTP Error 401 401.5 Unauthorized: Authorization failed by ISAPI/CGI app

This error indicates that the address on the Web server you attemped to use has an ISAPI or CGI program installed that verifies user credentials before proceeding. The authentication used to connect to the server was denied access by this program.

This is a known IIS 4.0 bug/feature, which is luckily easy to fix.
