Using the WebDAV Redirector

Microsoft has created a new WebDAV extension module that has been completely rewritten for Windows Server 2008 and Windows Server 2012. This new WebDAV extension module incorporates many new features that enable web authors to publish content better than before.

This document walks you through using the WebDAV redirector to publish content to an existing web site that has the new WebDAV module installed.

Installing the WebDAV Redirector

Prerequisites

You must be running one of the following operating systems:

• Windows Vista, Windows 7, or Windows 8
• Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012

You must be connecting to a web server that already has the WebDAV module installed.

Windows Vista, Windows 7, Windows 8, or Windows 8.1

If you are using a desktop operating system like Windows Vista, Windows 7, Windows 8, or Windows 8.1, the WebDAV redirector is already installed.

Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, or Windows Server 2012 R2

If you are using a server operating system like Windows Server 2008 or later, you need to install the Desktop Experience feature. To do so, use the following steps:

1. Start the Windows Server Manager.
2. In the tree view, highlight the Features node.
3. In the details pane, click Add Features.
4. In the Add Features Wizard, check the Desktop Experience box, and then click Next.
5. Click Install.
6. When the Add Features Wizard has finished, click Close.
7. Click Yes when promoted to restart the computer.

Mapping Drives using the WebDAV Redirector

Once the WebDAV Redirector has been installed, you can map drives to your web site using WebDAV. There are two ways to accomplish this:

Method 1: Mapping Drives using the Map Network Drive Wizard

To map a drive using the Map Network Drive Wizard, use the following steps:

Open the Map Network Drive wizard. This can be accomplished by using one of the following methods:

Troubleshooting the WebDAV Redirector

The following list of error conditions is designed to help troubleshoot situations that you might see when working with WebDAV.

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 67 has occurred.

The network name cannot be found.

This can be caused by one of the following conditions:

• IIS is not installed or is not running on the server that you are attempting to connect to.
• You have not installed the WebDAV Redirector on your client system.
• The WebClient service is not running on your client system.
• You have not enabled WebDAV on your web site.
• You are using Basic Authentication and connecting to your web site using HTTP instead of HTTPS.
• You are connecting to a web site on your local network that is using Fully-Qualified Domain Names (FQDNs) for name resolution, your web site uses Windows Authentication, and you have not added the web site’s FQDN to the proxy server bypass list on your client.

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 1920 has occurred.

The file cannot be accessed by the system.

This error occurs when the account that you are using does not have an authoring rule created for it.

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 5 has occurred.

Access is denied.

This can be caused by one of the following conditions:

• The account that you are attempting to use does not exist.
• You entered the incorrect password for the account that you are using.
• The account that you are using does not have sufficient permissions for your web site’s content.
• You have not enabled any authentication methods for your web site.

When attempting to map a drive to a WebDAV site using HTTPS, you are prompted with the following dialog:

This occurs when the SSL certificate for the site that you are using does not match the name of the address that you used. For example, you are connecting to a site named www.contoso.com , but your SSL certificate was issued to shopping.contoso.com .

When attempting to map a drive to a WebDAV site, you receive the following error:

System Error 1244 has occurred.

The operation being request was not performed because the user has not been authenticated.

This can be caused by one of the following conditions:

• The server that you are connecting to does not have any authentication methods enabled.
• The WebDAV client is running into the problems that are described in KB941050 or KB943280.
• The logon type for content on a UNC share is incorrect; this setting is configured in the Physical Path Credentials Logon Type option in the Advanced Settings for a website or application, and is defined by the logonMethod attribute for the virtualDirectory settings for a website or virtual directory. For example: if the directory for your website’s content is on a network share, you may need to change your settings from Clear Text to Network depending on your network configuration.

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 59 has occurred.

An unexpected network error occurred.

This can be caused by one of the following conditions:

• The web site that you are attempting to connect to has been stopped.

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 58 has occurred.

The specified server cannot perform the requested operation.

This error occurs when the WebDAV server does not have the correct host name in its bindings. For example, if you have DNS entries for contoso.com and www.contoso.com , but you only have an IIS binding for contoso.com , you will see the error when you attempt to map a drive to www.contoso.com .

When attempting to map a drive to a WebDAV site, you receive the following error:

System error 224 has occurred.

Access Denied. Before opening files in this location, you must first add the web site to your trusted sites list, browse to the web site, and select the option to login automatically.

This error occurs when the WebDAV site is not trusted by the WebDAV redirector. To resolve this issue, you need to add the website’s URL to the list of trsuted sites. To do so, use the following steps:

• Open the Windows Control Panel.
• Open Internet Options.
• Click the Security tab.
• Click the Trusted sites icon.
• Click the Sites button.
