-or-

The folder &quot;http:// &quot; isn't accessible. The folder may be located on an unavailable volume or protected with a password.

The following issues may also occur:
 * No Web folders are visible in the Open File dialog box of an Office 2000 program.
 * When you attempt to create a new Web folder, the Web Folder Wizard finishes without errors but the Web folder is not created.

After the key has been deleted, run Detect and Repair on Office 2000 or one of the stand-alone Office products installed.</li> Update or reinstall the latest version of the Microsoft Data Access Components (MDAC).

Before you update or reinstall MDAC, run the Component Checker from the following Microsoft Web site to determine your current version of MDAC:

http://msdn2.microsoft.com/en-us/data/aa937695.aspx

After you determine which version of MDAC you have, install each version in increments until you have installed the latest version. For example, if you have MDAC 2.1, you will need to install MDAC 2.5 before you install MDAC 2.6.

To download MDAC, visit the following Microsoft Web site:

</li> <li>Verify that the MSDAIPP folder exists and that it is not set to Read-Only. <ul> <li>On Microsoft Windows 95, Microsoft Windows 98, and Microsoft Windows Millennium Edition (Me), the MSDAIPP folder is located at:



</li> <li>On Microsoft Windows NT 4.0 the MSDAIPP folder is located at:

%WINDIR%\Profiles\ \Application Data\Microsoft\MSDAIPP

</li> <li>On Microsoft Windows 2000 the MSDAIPP folder is located at:

%HOMEDRIVE%\Documents and Settings\ \Application Data\Microsoft\MSDAIPP

</li></ul>

If the MSDAIPP folder is missing or Read-only, or if the %WINDIR%\Nethood folder is set to Read-only, you may receive the following error message:

The Folder <HTTP Address> is no longer available.

If the MSDAIPP Folder does not exist, create the folder at the appropriate location depending on the operating system that is in use. If the folder is set to Read-only, remove the Read-only attribute from that folder.

MORE INFORMATION
Web Folders are a new Web authoring component included with Internet Explorer 5 and Office 2000. With Web Folders, you can manage files by using the familiar Windows Explorer or My Computer interface on Web servers that support the WWW Distributed Authoring and Versioning (WebDAV) or Web Extender Client (WEC) protocols. These protocols are defined as follows:
 * WebDAV is an extension to the Hypertext Transfer Protocol (HTTP) that extends the base set of HTTP methods to include basic file functions such as copying and moving resources, creating folders or resource collections, locking and unlocking resources, and setting and retrieving resource properties.
 * WEC is a Microsoft Office 2000 protocol that is used for Web publishing, and is usually implemented through the use of Microsoft FrontPage Server Extensions.

Web Folders is installed as a namespace (or shell) extension to the operating system with an icon in My Computer (root object in Windows Explorer) or in My Network Places in Windows 2000. This root object is a container for shortcuts to your Web publishing sites and it enumerates HTTP URLs as files and folders. You can use Windows Explorer to view, move, copy, rename, delete, create new, and sort files, a- well as group files by properties and view property sheet information for files in a Web Folder, depending on your authoring and security permissions on the Web server.
