If you open a network folder in Windows Explorer and then try to open a file from or save a file to that folder, the associated program may report a sharing violation, return an "access denied" message, or open the document as read-only. Typically, this problem occurs when you open a network folder and then double-click to open a Microsoft Word or Microsoft Excel file. The document opens as read-only.
This problem may occur when the Microsoft Windows XP Shell Column Handler reads the contents of the file in the network folder to obtain additional information, such as author or subject, at the same time that the associated program tries to open or save the file.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Microsoft Windows XP Service Pack 2.
By default, after the hotfix is installed, the Windows XP shell will no longer try to read the whole file to extract file attributes if the file is located on a UNC share, but the whole file may still be read if the data is on a mapped drive. The pop-up descriptions for folder and desktop items will show only the type, size, and date modified for files that are located on the network.
