FYI: internal commands are running must faster. Each SHELL and RUN command
creates his own virtual dos environment which slows down your script speed.

We agree with NTDOC that internal USE command works great.
Possible problems with (NET) USE can be:
persistent drive or already used drive
By internal command your script can be aborted. A RUN or SHELL command doesn't
have influence on your script, but by using RUN or SHELL you doesn't have
the capability to use the @error/@serror capability.
