Can' use a share

I have a domain with few computers sharing files with each other no
problems
I added a laptop to the domain and I can do remote desktop with it but
I can't use it shares or drives from other PCs on the domain.
Even when I have the laptop's firewall off, when I try something like
'\\laptop\c$' (file://\\laptop\c$) I get the error
"The remote device or resource won't accept the connection"

What Can be done to fix that?
