James,

Thanks for the response. AFAIK we are using the ViewFormPagesLockDown
feature.

Some work was done previously with permissions but as I understand it, that
only resolved issues for internal staff accessing the site; the problem
still remained for external anonymous users.

Cheers,

Chris

Subject:  RE: Help with 401 errors on public site

I know it might not be immediately helpful, but on the topic of 401¹s in
Internet facing sites there is something to be to be aware of that might be
contributing to your 401 woesŠ
 
If you use the ViewFormPagesLockDown feature (as all public facing MOSS
sites should) it has security ramifications such that if you break security
inheritance at the list or item level, Anonymous Internet users will lose
access (regardless of the permissions granted), and be presented with 401
errors.
 
It doesn¹t matter if you specifically grant access to the items/lists, and
toggle the Anonymous setting ­ Internet users will lose access if the
Special Permission level is not inherited.
 
So for Internet sites you must choose between
·         Enabling the ViewFormPagesLockDown feature and living with web
level security only

·         Not using ViewFormPagesLockDown and having all your system forms
available (like View All Site Content)

 
I logged an incident with Microsoft Support ­ and got the ³By Design²
resolution.
 
Cheers,
                James.

Subject: Help with 401 errors on public site
 
Hi,

We have a public facing internet site and we're seeing a lot of 401 errors
in Web Trends.

The errors are occuring for links such as:

http://www.oursiteurl.au/Pages/

We've got a couple of questions that we're looking to resolve so was hoping
to get some input from the list.

1. How do we find any links that exist within the site that are linking
directly to a /pages/ link as it appears that somehow people are being taken
to this from a link but we're not aware of them; all links we can find are
to a specific page within the library.

2. How have people implemented work arounds at the /Pages/ level to redirect
to the default.aspx page in the library and avoid a 401 error? I've found
some sites; the WA one being a very good example
(http://www.westernaustralia.com/au/Pages/Welcome_to_Western_Australia.aspx)
where this is done.

Anyone on the list had any involvement with that site or others and could
share info or point to resources?

Thanks in advance.

Chris
