One PC not connecting to local network

Hi,

I am using tree WIN10 (and one WIN8) PCs in a network. I'll just call them A, B, C and 8. (8 being the WIN8).

A is the PC where my scanner and printer are attached (USB), and the one with the largest and best monitor, so I do most photo editing here.

B is mainly the "photo server" - a laptop where I attach my camera, store the photo files and administer backup of photo files.

C is a "every day general use" laptop, where I can easily view photos on our television flat screen (guests and to).

8 isn't that important in this, so I'll leave it out for now.

The problem is - A and B connects just fine. (So do 8).
C did use to work, but is not shutting itself out from the network, requiring login name and password.

However, I have checked - there is nowhere any requirement for password. Not in C, not in A and B.

They are all connected through WIFI - one access point and a "repeater" of some sort.

Have you checked device management? rt, click on the windows icon. Do all your drives show up and are they any for the c drive. if not go to the device manager and disable a usb storage port, then check again for the reappearance of your drive/ you may have to disable one or more, but eventually, if it hasn't resurfaced already, you will see the drive show up. If you had to turn off(disabled) more than one it's ok so long as you haven't lost any other drives. Be sure the drive letters and paths line up

Run this on every pc xan it see it and note which is master browser https://www.nirsoft.net/utils/netbios_scanner.html

Thank you - it is the C PC that is master, that is, the problem PC. The two (three) other is ok.

However, running the test several times reveals some instability? It is not always the same PCs are listed, and once one is listed twice.

Checked that - everything seems just fine.

The C PC is master. This is the problem PC.
