I am trying to modify permissions of a specific file or files and getting an
error of invalid arguments.

cacls "%SystemRoot%\Inf\Usbstor.pnf" /t /e /c /g "DOMAIN\DOMAIN USERS"

I'm entering that into the command prompt. I also used "c:\windows" in place
of systemroot. Also tried with or without quotes.

Here are the options for the /G switch:
/G usererm Grant specified user access rights.
Perm can be: R Read
W Write
C Change (write)
F Full control
It's R, W, C or F. There is no "D"!
