Domain User being Prompted on Anonymous External SharePoint

We have had an SSL External SharePoint 2007 requiring login site since
January. Yesterday just release our first External Anonymous SharePoint
site. Users from the outside work great; however, my domain users are being
prompted when they try to open up a document. In watching a network trace
with the occurrence it seems to have something to do with the Microsoft
Office Protocol Discover call that is made when the call for the document to
open. I realize that a second call is made when the request for the document
to open. The users do not have the problem in Fox Fire only in IE. Also I
have the WebDav accessibility is turned on in IIS. Any suggestions to a
solution.

Hi Terrie,
Can you please explain what you did?

Do all users "login" to the same site .. External users, internal users

Did you extend a web application to have multiple authentication providers?

Have you tried put the URL for the site to trusted sites in IE7 or local
instranet for IE6?
