Slow response working with WebDAV resources on Windows Vista or Windows 7

S’applique à : Windows 7 EnterpriseWindows 7 Home BasicWindows 7 Home Premium

Symptoms


You are using Windows Vista or Windows 7 to access WebDAV resources. No proxy server is between your client machine and the WebDAV resource. You may experience longer than expected delays when:
  • Opening a WebDAV folder
  • Copying files to or from a WebDAV folder
  • Changing from one folder to another on the WebDAV folder

Cause


When WebClient issues a WebDAV command, it checks for a web proxy server before issuing each command. When Auto-Proxy detection is enabled and there is no proxy server in the environment between the client and WebDAV resource, WebClient waits for the timeout of Auto-Proxy detection. Command completion will take longer due the wait for the Auto-Proxy detection timeout.

Workaround


Confirm that there is not a proxy server between the client and the WebDAV resource. If there is no proxy server involved, de-select Automatically detect settings in the LAN Settings for Internet Explorer:
  1. Start Internet Explorer.
  2. Click Tools, and then click Internet Options.
  3. Click the Connections tab, and then click LAN Settings.
  4. De-select Automatically detect settings.
  5. Click OK and test functionality.
