From the error message that you cited, I can think of only
one place to look (given that the NTFS permissions on the
drive and folders you're working with are correct).
Start mmc and add the group policy snap-in.
Under Local Computer Policy\Computer
Configuration\Security Settings\Local Policies\Security
Options, make sure that driver and non-driver
installations are allowed (I'm writing this from a W2K
machine 'cause I'm too lazy to walk across the room, but I
think the paths are the same). These settings would not,
however, affect your ability to delete folders and files.
Then under both Computer Configuration and User
Configuration, in their Administrative Templates section,
make sure that everything is either allowed or not
configured.
One other thing to check: Is Simple File Sharing enabled?
If so you might get funny results. For instance, if a
folder is marked as "private" by one user, everyone else
might be able to view the contents of the folder but not
be able to change its contents. If that's the case, log
in as each user, right-click the folder, and make sure
that it's not marked as "private".
Can you give any more details on the error messages?
