Very Hard to conect to my NAS y trouble with users

HI, first sorry for my english (my fisrt language is spanish).

I work in the university and use 2 NAS, but with the WD My Cloud all time have problem for login. Is extremely slow (need sometime wait 2 to 5 or 10 minutes for login). And after need wait over 1 or 2 minutes for every clic when changes windows. My network is very big 152.74.xxx.xxx (university). But the NAS from IOMEGA work very fast and never have problem with conection.

My other problem is the last days I creat news folder for share and create new users but the news users can login in the folders, in total the users are 15 persons.

thanks
