Symptoms

Consider the following scenario:
  • You install Internet Information Services (IIS) on a server that is running Windows Server 2008 R2 or Windows Server 2012.
  • You configure the server as a Web Distributed Authoring and Versioning (WebDAV) server.
  • You map a network drive to the WebDAV folder on a client computer that is running Windows 7 or Windows 8.
  • You start Internet Explorer 9 or Internet Explorer 10 on the client. On the Tools menu, you click View downloads, click Options, set the network drive in the Default download location box, and then click OK.
  • You access a web server from Internet Explorer 9 or Internet Explorer 10, select a file, and then click Save.

In this scenario, Internet Explorer stops responding for a while, and the file cannot be saved.
