Best Resource for Networking Problems?
Discussion
I have 5 Win10 PCs networked. One is a Backup.
All PCs can see each other and ping each other.
Until recently all could access each other and the backup using the "Everyone" access without a password.
Yes I know that it's insecure but I am the only user and generally only one computer is switched on.
Now after a failing PSU causing corruption I had to reinstall Win10 on the offending computer "A".
Computer "A" can access all computers except backup.
Backup can access computer "A" without problems.
I have written myself a Word doc of all the things that I've tried, websites I've visited, without success. Too long and boring to post here.
But has anyone found a really good logical A-Z of solving networking problems? Hunting and pecking through the internet is just an exercise in frustration when it's not an easy fix. It's not that I don't have experience. I've had home networks since the days of 10Base2 coax!

Strange isn't it when you give up for a few minutes, ask for help and then an idea hits you.
Computer "A" was updated to Win7 then Win10. It's fast enough for email.
I checked in the hosts file and found that IP address for the backup computer was there with the "correct" IP number. Perhaps required a long time ago.
I then checked on the backup computer and found that for some reason the network address had changed to DHCP therefor computer "A" was pointing in the wrong place but as "net view" only shows computer names and not addresses I could not see the problem.
Well the problem was me.
I hope that this might help someone else.
