When I click on the sharing folder in sys pref there are no options avail.

I am trying to set up sharing between my two macs, but when click on the sharing folder in system preferences, there are no options visible. This only occurs on one of my macs. but on my 10.7.4 lion mac, there are no options.

All other options of all other system preferences are there, just not my sharing options. I have tried to download updates to 10.7.4, but it has not fixed the problem.

PLEASE HELP!!!!
