Windows 2000 office 2000 permissions

I have a w2k server and 15 98/95 workstations running terminal services to the server. When I initially set the users up in the active directory users and computers screen they all had administrator rights. I then installed office 97. Since then i have removed the administrator rights for all but 2 of the users. My problem is that the rest of the users now cannot access the spell checker function of the office product. When i try to install it for any particular user I go to the set language option on the tools menu of word. This does not do anything and there is no error message. I have tried everything short of a complete uninstall of Office but cannot get it to work.
