Can't connect to laptop on network but laptop can connect to all other

Tried everything suggested including a 'Network Reset'. Regrettably, nothing works!

Have you tried connecting to your shares by creating a link using that Add a Network Location from the menu on
This PC page. That will add an individual share and it appears as a shortcut on C:\ . It's a PITA to add many shares using that method but at least you've got a connection .

Bingo! Problem solved but may only apply to me. I finally realised (Doh!) that of the 4 machines on my network, the only one giving problems was the Acer laptop. I then remembered that it's the only one which was using AVG firewall. I turned off AVG firewall and turned on Windows firewall - result! All back to normal.

I now need to RTFM for AVG to see what settings are required in AVG firewall so everything works.

I hope it may point a way for others. Thanks a million to all who tried to help.
