Adding rights to files without changing Ownership - special case! BATCH command needed!

I tried to use the cacls command with the /E switch to do this.

The /E switch edits permissions rather than replacing them.

I wanted to give READ access to Everyone to a folder USRPROFILE
and everything in it and below it, without changing any other
permissions using this command:

CACLS USRPROFILE /E /T /G Everyone:R

command returns "Access Denied" (runned in correct
directory/folder).

I am Administrator on this machine. OWNER is one of domain user
group, but i cant even see what permissions apply without
changing ownership back to Administrator, and after adding
Everyone changing ownership back to User created it.

I have 300+ folders with same problem. Mostly PROFILE data.
Problem is that quotas cant be calculated in PROFILE subfolders
so i cant really keep track whos using most of network drive.

Please help!
