Redirect page if authentication fails

Question

Hi, it seems there should be an easy answer to this although whatever we try it doesn't seem to work.
Basically, we would like to redirect the user to a given page if the authentication to the SharePoint site fails (i.e. the standard windows login prompt pops up three times - we are using windows authentication). No matter what option we try it always
ends up bringing the user back to a blank page.
We have tried writing a HttpModule (and catch the if Response.StatusCode = 401), which doesn't seem to fire any events if the user is not authenticated. We have tried writing a HttpHandler, but of course we can redirect the user if there is an error code
but can't continue onto the desired site if not. We have tried doing the following in the web.config:
<customErrors mode="Off">
      <error statusCode="401" redirect="http://social.msdn.microsoft.com"/>
</customErrors>
Which doesn't work, again taking us to a blank page. Has anyone any ideas what we are doing wrong?!

Wow, blast from the past. I'm afraid we didn't, it was incredibly frustrating as we had this working on older versions of Sharepoint. Maybe you'd have better luck posting on an ASP.NET forum. We are looking at doing the same thing in SharePoint 2010 very
soon so if I find a solution I will post a link on this forum. Sorry about that!
