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

Windows Vista, Windows 7, Windows 8, or Windows viii.one

If you are using a desktop operating organisation similar Windows Vista, Windows seven, Windows 8, or Windows 8.ane, the WebDAV redirector is already installed.

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

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

  1. Start the Windows Server Manager.

Mapping Drives using the WebDAV Redirector

In one case the WebDAV Redirector has been installed, you tin map drives to your spider web site using WebDAV. At that place are two ways to accomplish this:

  • Mapping Drives using the Map Network Bulldoze Wizard
  • Mapping Drives from a Command Prompt

Method i: Mapping Drives using the Map Network Drive Wizard

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

  1. Open the Map Network Bulldoze sorcerer. This tin be accomplished by using ane of the following methods:

If you receive an error, please see the Troubleshooting the WebDAV Redirector department for more data.

Method ii: Mapping Drives from a Control Prompt

To map a drive from a command prompt, use the post-obit steps:

  • Click the Windows Offset icon.

  • Click All Programs.

  • Click Accessories.

  • Click Command Prompt.

If you receive an error, delight come across the Troubleshooting the WebDAV Redirector section for more information.

Troubleshooting the WebDAV Redirector

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

  1. When attempting to map a drive to a WebDAV site, yous receive the following error:

    System error 67 has occurred.

    The network name cannot be found.

    • The WebClient service is non running on your customer system.
    • You accept not enabled WebDAV on your web site.
    • You are using Bones 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 proper name resolution, your web site uses Windows Authentication, and you take not added the spider web site's FQDN to the proxy server bypass listing on your client.

  2. When attempting to map a drive to a WebDAV site, you receive the post-obit mistake:

    Organisation error 1920 has occurred.

    The file cannot be accessed by the system.

    This error occurs when the account that yous are using does not accept an authoring dominion created for information technology.

  3. When attempting to map a drive to a WebDAV site, yous receive the post-obit error:

    Organization error five has occurred.

    This tin be caused past one of the following conditions:

    • The server that you lot are connecting to does not accept whatever authentication methods enabled.
    • The WebDAV customer is running into the problems that are described in KB941050 or KB943280.
    • The logon blazon for content on a UNC share is incorrect; this setting is configured in the Physical Path Credentials Logon Type pick in the Advanced Settings for a website or awarding, and is divers by the logonMethod attribute for the virtualDirectory settings for a website or virtual directory.

This can atomic number 82 to overwritten information and errors like "File Non Constitute" or "Windows cannot admission <file name>".

  • To resolve the file not found error, ready the FileNotFoundCacheLifeTimeInSec to 0 using Change the timeout enshroud value for WebDAV.
  • Employ unique file names, never differ file names by case.

WebDAV Redirector Registry Settings

There are several settings that command the behavior of the WebDAV redirector that can exist configured in the post-obit registry central:

HKLM\Arrangement\CurrentControlSet\Services\WebClient\Parameters

The following table details the various settings and values that are available.

Note
