You might want to try "Network Magic" to set up and maintain your LAN.

I have been using it for a couple of years and have avoided a lot of 
frustration.

But now, computer A can see one of the two shared folders on B, but not the second folder even with the Win firewall turned off..  A cannot see either of the shared folders on C. I turned sharing off and on again on, no change.. B can see the shared folders on A but cannot open them (access denied). B and C can see and access folders on each others computer. C does not see the shared folders on A.  So A seems to be the problem.
