When you use Microsoft Internet Explorer 6 to access shares on a Microsoft Windows NT 4.0-based server or a Microsoft Windows 2000-based server, access to the shares may appear to stop responding (hang).
Note You may gain access to the requested shares if you wait a long time, for example, 10 minutes.
This problem may occur if the Webclient service is running.

Microsoft has confirmed that this is a problem in Microsoft Internet Explorer 6.
WebDAV is the redirectory that permits a Web server to share a folder and permits a client to access the files in the folder by using a universal naming convention (UNC) name in HTTP protocol format. When the client sends a read or write request to the Web share, the WebClient service initiates a Send or Receive request to the Web server on behalf of the client. The WebClient service calls the WinINET API to handle the HTTP protocol. Because WebClient runs as a service, the WinINET API sends a pop-up dialog box which is transparent to the client. As a result, the send or receive request by the client appears to stop responding (hang).
