-------------------------------------------------------------------------------

SYMPTOMS
========

After you install Windows NT version 4.0 Service Pack 4 on a workstation or
server, you may receive the following error when you run a script or batch file
that connects to a resource, runs an application, and then disconnects from that
resource:

  The device is being accessed by an active process. More help is available by
  typing NET HELPMSG 2404.

An example script would be similar to the following:

  net use q: \\servername\share
  q:
  login.bat
  c:
  net use q: /d

CAUSE
=====

The redirector holds a reference to the File Control Block (FCB) in the cache. A
fix to the Redirector (Rdr.sys) in Service Pack 4 was made to check for open
references before tearing down the session.

==========
