We have an issue with copying files with the DOS copy command and NW
client 4.91 SP3. We have thousands of batch files which copy a file from
a subfolder to the parent one using the following command:

copy subfolder\file file

We use this copy command for several years and all worked fine until
SP3. When sending the command, we get an 'access denied' error.

I have doublechecked it on my workstation first with the SP3 version
which provided the error and the SP2 version which works fine.

Can anyone confirm this bug?

Thanks, Peter
