3.50 WINDOWS kbtool

The information in this article applies to:

Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

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.

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.
