If you use Windows Explorer on a Windows XP-based client computer to perform a search for files or folders on a computer that is running Microsoft Windows NT 4.0 Workstation, Microsoft Windows NT 4.0 Server, or Microsoft Windows 2000 Professional, the connection to the files may appear as being left open on the target computer. This issue occurs if you search by using the A word or phrase in the file search option.

If you view the open file connections on the server, the files may correspond to .xls files, some types of CAD files, or both. The files stay open until you log off.


The Microsoft Office Indexing filter (Offfilt.dll) may leak file handles when you search from the shell. Offfilt.dll is used to index Microsoft Office files.


To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
