The Microsoft WebDAV 7.5 for IIS 7.0 helps you enable powerful publishing capabilities for your Web environment.

  • Microsoft has created a new WebDAV extension module that has been completely rewritten for Windows Server 2008. This new WebDAV extension module incorporates many new features that enable web authors to publish content better than before, and offers web administrators more security and deployment options. This new WebDAV extension module supports a wide range of features and improvements, and the following list contains several of the improvements in this version:

    • Integration with IIS 7.0: IIS 7.0 has a brand-new administration interface and configuration store, and the new WebDAV extension module is tightly integrated with this new design. The old IIS 6.0 metabase is gone, and a new configuration store that is based on the .NET XML-based *.config format has taken its place. In addition, IIS 7.0 has a new administration tool, and the new WebDAV extension module plugs seamlessly into that paradigm.

    • Per-site Configuration: WebDAV in IIS 7.0 can be enabled at the site-level, unlike IIS 6.0 which enabled WebDAV at the server-level through a Web Service Extension.

    • Per-URL Security Settings: The new WebDAV extension module supports per-URL authoring rules, allowing administrators to specify custom WebDAV security settings on a per-URL basis. These authoring rules are separate from the IIS 7.0 per-URL authorization rules, thereby allowing one set of security settings for normal HTTP requests and a separate set of security settings for WebDAV authoring.

    • Support for shared and exclusive locks: The new WebDAV extension supports both shared and exclusive locks to prevent lost updates due to overwrites.

System Requirements

Operating Systems: Windows Server 2008

    • Internet Information Services 7.0 must be installed, and the administration tool should be installed if you are going to manage the WebDAV extension module using the IIS 7.0 user interface.

    • You must install the WebDAV extension module as an administrator. If User Access Control (UAC) is enabled, you must use the “Run as Administrator” option when installing.

    • IIS 7.0 supports a new shared configuration environment, which must be disabled on each server in a web farm before installing the new WebDAV extension module for each node. Note: Shared configuration can be re-enabled after the WebDAV extension module has been installed.

Installation Instructions

  • Click the Download button on this page to start the download, then do one of the following:
    • To start the installation immediately, click Open or Run this program from its current location.
    • To copy the download to your computer for installation at a later time, click Save or Save this program to disk.
    Installing this extension module requires full administrative permissions. This is best accomplished using one of two methods:
    1. Log in to your computer using the local "administrator" account before installation.
    2. Copy the download to your computer, then log in using an account with administrator privileges and opening a command-prompt by right-clicking the Command Prompt menu item that is located in the Accessories menu for Windows programs and selecting "Run as administrator", then typing the command listed below to run the installation:

      msiexec /i webdav_x86_75.msi
    Note: The above steps are required because the User Account Control (UAC) security component in the Windows Server 2008 operating system will prevent access to your system. For more information about UAC, please see the following documentation:
