Networking :: Devices On Local Network Unreachable

From a PC (called PC1 later on; running W10), I do not see other PCs or multimedia boxes connected on my local network.

Using 192.xx.yy.zz doesn't work.

From a W10 tablet PC (called PCt later on), I see other connected devices: Dune HD and PC1. From PCt I can even navigate into PC1 directories.

In PC1 Network and Sharing Center, I cannot enable file sharing.

When clicking on the button to activate it and then saving the changes, I notice, when reopening the parameters window, that it hasn't been changed. It remains disabled.
