SYMPTOMS
When you modify any file on a Web Distributed Authoring and Versioning (WebDAV) share, you may notice that the last modified time value is not updated correctly.



CAUSE
This problem occurs because the WebDAV mini-redirector in Windows XP attaches the Win32LastModifiedTime property to the file to indicate the last modified time. However, this value is incorrect. To attach this property, Windows XP uses the propattach command when the file is created or modified. Even if the getlastmodified property is present, the WebDAV mini-redirector gives priority to the Win32LastModifiedTime property over the getlastmodified property.
