maybe a bug by ms to not allow limiter users of the same system but the limited users of other systems to access admin files.

Ensure that the documents folder are not password protected my documents>Properties

Another thing that mite help u is changing the limited users into power users
U can do this by going to CP>Admin tools>Com Mgmt>Users and changing the limited users to power users. Dunno whether this will work 4 sure
