Network not quite working

I have a small network with 5 pcs on it - until last week everything was working fine but after a disaster I had to reinstall the OS (w10 pro 64bit) on one of the machines and since then have had a few issues.

From any of the other machines I can see and access shared folders from all the other machines, including the one I have just done the reinstall on. However from the updated machine I cannot read any of the other machines although they appear on the network list and can be read by all the other pcs - I simply get a message saying "pcX is not accessible - you might not have permission etc etc. The odd bit is that I can see the media from one machine and user from the other which appear in a separate pane on the explorer. When accessing any of the other machines from any machine apart from this one, everything works fine - I can read change and save files between machines as normal. I have checked the user names is the same on each machine - nothing wrong with cables etc -

Tried rebooting all machines and reconnecting and get message about missing protocol - the "self repair" then fails and flags the same issue.

Can someone please help me understand what may be wrong here!

First thing I would check is make sure that the computer having the problem is to go into Network and Sharing Center and make sure the connection is set to either Private or work and not public



If it's set to public see if this Tutorial helps
How to Set Network Location to be Public or Private in Windows 10

I would also try the trouble shooter I labeled as 2 in my picture above if that does not help.

If this does not help post what you have tried and the results and either me or another TenForums user would be glad to help.
