MORE INFORMATION
When you copy a file to a WebDAV server by using the Windows XP WebClient, this process involves two internal steps:
 * 1) WebClient copies an empty file (0 bytes) and then sets the file attributes.
 * 2) WebClient copies the file contents and then sets the file attributes.

Notes
 * If you copy an empty file to a WebDAV server, WebClient performs only step 1. Therefore, the time stamp is correct in this situation.
 * The Microsoft Data Access Internet Publishing Provider DAV client does not support DAV attributes.

This problem occurs only in the following installations:  Windows Server 2003 Windows Server 2003 SP1 Windows XP SP2 Windows XP SP1 with the hotfix from the following Microsoft Knowledge Base article installed:
