SYMPTOMS
========

When you start the Schedule service and then enter an AT command to instruct the
COPY command to run at a specified time, the COPY command does not run at the
specified time and the following message appears in Event Log:

  Event ID: 7901
  Source: Schedule
  Type: Error
  Category: none

  The system cannot find the file specified.

NOTE: These symptoms occur when you attempt to use any internal command with an
AT command.

WORKAROUND
==========

To run any internal command from the AT command use "CMD /C" syntax. For
example:

  AT 10:00 CMD /C COPY C:\*.* C:\TEMP

Under Windows NT version 3.1, the "CMD / C" switch was not necessary. However,
this functionality has changed for Windows NT version 3.5 to correct problems
with passing arguments to commands.

NOTE: XCOPY, CHKDSK, do not require the "CMD /C" command because they are not
internal commands.
