Win 2000 & DOS

By jdwilson ·
I am running Win2000 connecting to a Netware 3.21 server running DOS 3.2 applications. All files are on the server.
The program ran fine untill we installed service pack 4 for Windows 2000.

My problem is the application
opens file 1 output,
reads file 2,
writes records from file 2
to file 1
then closes both files.

Then the application calls a DOS command which copies file 1 over top of file 2.

MOVE "COPY HOLDCOPY.ISM HOLDPICK.ISM>NUL" TO FILENAME.
DISPLAY FILENAME UPON COMMAND-LINE.
CALL X"91" USING RESULT,FUNKTION,PARAMETER.
IF RESULT NOT = 0
PERFORM ERR-RTN.

It appears that the application failes during the copy and falls out of the program.
The file is 6 mb. Could this be a buffer or files issue.
I am using the default config.nt file which only has files=40. I am not using any custom PIF file.

dos=high, umb
device=%SystemRoot%\system32\himem.sys
files=40

This started happening after we installed the windows update 'Service pack 4'. The application runs fine on a pc that has not been updated.

Can anyone please share any information on WIN2000 and DOS, why this might be happening.

Thanks,
Jim
