Hi Mark,

I'm not quite sure I'm following from the subject of your posting to the description of the issue.

What are the file types that you're trying to open and are you saying Office is making the requests or IE?

If you're using a prior version Webfolders feature that isn't supported in Office 2007 on Vista, but WebDav (via the Vista Dav
redirector) is supported.

We have numerous machines running Vista and Office 2007 that receive extra
password prompts when trying to view a document from an intranet web site
that is in the "Trusted Sites" zone in IE. They will be prompted three times
before receiving the document. Clicking 'cancel' on the authentication dialog
opens the document.

We have tracked the issue to several extra HTTP OPTIONS and PROPFIND
requests that are being issued to the web server as the document is opening.
Some of these requests are to the folder containing the document, others are
to the root of the site. The web site does not support WebDAV, and does not
need to.

How can we eliminate the excess OPTIONS and PROPFIND requests so our users
are not continuously prompted for passwords?

Thanks,
Mark >>
