Been away a couple of days so only just got back to trying to sort it.
The frustrating thing is that six months ago using Homegroup it took a matter of minutes to set up and has worked seamlessly until the latest Win 10 update.
Did a bit more poking around and thought I had cracked it as I found the laptops network profile had somehow been reset to Public, I changed it back to Private but it has made no difference.
I can see the laptop on my desktop but not access any files, the laptop cannot see the desktop or itself either but can see the wireless printer.
