SYMPTOMS
========

If you use Windows Explorer on a Windows-based computer to copy a file to an SMB
(Server Message Block) server using the Microsoft Client for Microsoft Networks,
the file may be truncated if the server's disk is full or nearly full.

The copy operation may seem to succeed, and no error message is displayed.
However, some data at the end of the file may be lost.

CAUSE
=====

This can occur if the amount of free disk space on the server is slightly less
than the size of the file being copied.

RESOLUTION
==========

To resolve this issue, make sure the disk on the network server contains
sufficient free space for the file being copied.

A supported fix is now available from Microsoft, but it is only intended to
correct the problem described in this article and should be applied only to
