Can't access to another Mac

I just purchased update of silver aTv yesterday.
Mainly I want to access the movie files from another Mac.

So, I access to NitoTV and try to get the network.
But, the screen show this message.
" Network Mount Failed!

Mount_smbfs: can’t get sever address
‘My com.LOCAL’:
Unknown host
Mount_smbfs: can’t get server address:
Syserr=Network is down

And AFP also
AFP is not enabled properly or is missing
Essential component, Smart Installer with a
1.0 recovery dmg in~/Documemt will fix this

Anyone have any solution to fix this problem.

Thank you in advance
