I found a promising thread bit Woops! It could not be found.
my specs are below

Firstly,
I can activate a wireless printer on the network. Can't print because it says, across the network, that it has run out of toner, but it is connecting.
If I log into the router, it shows a list of 5 connected devices.

I am trying to access another Win 10 PC on our home network.
I tried clicking on Network in Windows Explorer.
- Only my own machine (Nick-PC) shows up.

Both machines are Win 64.
Both machines are using the same router and 28.GHz band. They are both connected and can use the Internet.
Network Discovery is on
File and printer sharing is on.

Any help appreciated

OK, Crudely I disabled the firewall on my PC and managed to see one of he other PCs.

In awed whisper...it was actually the PC I wanted!

I then set the folder I wanted to share, on the other PC, and all seems good. I can see that folder on my PC.
Strangely, the Firewall reinstated itself after 15 minutes, but I could still the other PC. If that does not stick then I will need to check configuring my firewall.
 
Windows tends to be too smart sometimes. The firewall setting for that network likely are set to public, it thinks you are directly connected to the internet. If you can change the setting to private network....which in effect almost turns the firewall off.

OK point taken.

However I use Comodo CIS as my security, at the very least because of the things you say. and its configuration is just a teeeny bit more complex than WinDoze's :D.. in fact it can be a real pain.
 
Most the actual firewall functions are pretty worthless. It would be extremely rare for another machine to attack from your own internal home lan. A true firewall is really only used in server environment where you are intentionally exposing the device to the internet.

Pretty much everything else and where the true risks are involve is malware and virus protection which tend to be different software since it is more application level rather than at low level network levels. Then again they are never going to stop the largest security risk which is the lazy person behind the keyboard that clicks "yes" please install some app that steals all my information. :)

Yeah but disabling the FW when I still have the Net available is my idea of a rude approach. I let it stay at its default of 15 minutes and as soon as I have a result I set it on again.

But yeah intra-network firewall is probably redundant.
- I see one risk in that until I check every machine in the LAN for internet safety, there is a risk of attack from one machine to another, surely. In these days of mobile phones and etc, I at least keep my LAN severely passworded in case a visitor cracks in, even by accident.
