Has anyone managed to get custom HTML forms to work with ISA2k6? I have followed exactly as per the help file but keep getting a "401: Unauthorised" error. If I remove the custom HTML form option from the web listener all works as per expected. I have some customers who are desperate to create custom forms for Sharepoint publishing, but don't seem to be able to get it to work at all....am I going mad and turning into a unihomed ISA admin??? :-) Is this a known issue/bug?
