I have a MOSS 2007 webapp with 3 sites:
- Root web with anonymous access enabled
- Subsite with anonymous access enabled
- Subsite with anonymous access disabled
When attempting to open site #3 while not logged in the user is prompted to enter their credentials. However, when those credentials are entered incorrectly 3 times, the prompts stop and the user is taken to a blank page. This page contains nothing, but inspecting IIS logs and using Fiddler 2 confirm that the server is returning 401 Unauthorized.
My question is: Why is a blank page being displayed instead of the standard "access denied" page? How can I either customize this blank page to something else, or get SharePoint to return the standard "access denied" page?
