Vista - Permission required for copying with ACLs using robocopy

Hello

I have the following issue: I want to copy files
including all their attributes and ACLs from my
computer to a network storage.

Our architecture is quite simple: a single domain
controller (I believe it's Windows Server 2008 x64)
and many desktops connected to domain.

Our administrator said we could do this with robocopy
utility which is installed on our desktops (which vary from Vista to
even Windows Server 2003 - just because it's more stable than
XP). She said we have all the permissions required for the operation.

When I tried to perform the following operation:

I get the message "Access Denied" on 3rd file. When I spoke to our admin,
she told me to find exactly what set of permissions should be defined, and she
will set it as I say.

So, can anyone explain me exactly what permissions/settings/anything else should
be existing for C:\MyDirectory and \\Storage\TeamA directories?

Should our users be defined in some specific way? Anything in policies?

I'll be really appreciative.

In addition: does robocopy perform privileges elevation? So it can accomodate the
minimal required level to perform the operation?

Thanks a lot.

Alex.
