Access is Denied when either adding or removing folder targets

Everything was going smooth until we added a third nas device to the DFS mix.
I've shared the folder and have given the appropriate rights to it, but when
I try to add the folder as target to an existing DFS share, comes back saying
access is denied. Also, when I try to remove a target folder from an
existing DFS share under DFS Management, comes back as Access Denied. I've
used my login, as well as domain admin, still the same. WHAT GIVES?????
