Sharing access not working on one of Five network PC's

Sharing access not working on one of Five network PC's. Access is blocked beyond the User's folder. two PC's sharing the same switch on the network are working fine but only one of them is shareable between the other three.Any Ideas?
Thanks in advance,

Have you shared all c: as that fatal you access c by using c$

and you fornat is wrong it should be from a cmd prompt
net use s: \\donstudio\c$ /user:don password

This is a private network and I own all PC's. Permissions are set to read on all 4 others.

Thanks for your Input.
Sincerely,

Turns out that once I shared a folder further on down the path via Brink's "share using security tab" everything is now clicking!
There are more icons in the network's sharing folder including "Users" plus the target folder but I can live with that!
Thanks again for yours and Brink's input.
Truly,
