The following list provides information about the values that should appear in place of the question marks in the preceding sample error messages. Note that only the original (and latest) versions of the redirector file (Vredir.vxd) are documented. Exception address values may vary on your computer if you have installed updates that are not listed. Also, the list is not guaranteed to be comprehensive, as not all redirector updates have been exhaustively tested for this problem. However, fault addresses tend to be near those that are documented:

In the preceding table, Windows 98 SE is used to represent Microsoft Windows 98 Second Edition, and DSClient is used to represent Directory Services Client.

Note: The problem described in this article has not been tested with Microsoft Windows 95. Note that the Directory Services Client can be installed on a Windows 95-based computer.

CAUSE

This problem can occur because when files are repeatedly opened and closed by using identical share modes, the redirector (Vredir.vxd) loses track of internal file-tracking structures, and erroneously schedules system events to close and deallocate file structures that have already been processed.
