How do you redirect to a "no access" or "unauthorized access" page. Better yet how can you redirect to a login prompt allowing users to enter creds. I don't need a custom error page.

thanks

In your webconfig, do something like this
 

 <customErrors mode="RemoteOnly" defaultRedirect="login.aspx">
           
        </customErrors>

I need to show the standard / default "unauthorized" error which should be different for each browser and version. It should be the typical 403 error not a custom error.
