SYMPTOMS

Consider the following scenario:

You are running a Windows Vista-based computer.
You use Windows Internet Explorer to access files on a Web Distributed Authoring and Versioning (WebDAV) site that resides on a local intranet site.

Note A Microsoft SharePoint Portal Server site is an example of a WebDAV site.

In this scenario, you receive a dialog box that prompts you to enter your user credentials.

This problem occurs if the following conditions are true:

You do not configure any proxy-server settings in Internet Explorer.
You access the WebDAV site on the local intranet site by using a single label host name, such as http://sites/ or http://mysps/.

This problem does not occur on a Windows XP-based computer that has Internet Explorer 6 or Internet Explorer 7 installed.
