I had a home network set up between my PC and a laptop. This worked well until, I assume, a Windows update broke it. I can see the laptop on my network from the PC and vice versa. I can drill down to some folders but whenever I try to view files in any of these folders I get a permission error.

I have all the relevant shares and permissions set up but there seems to be no way that this is going to allow me access the folders. Is there any way I can "delete" the network and start again or any other way round it. I have tried all the common solutions I can find on the Internet and none of them work.
