We have one machine which cannot see the rest on the domain under the network tab in File Explorer.
We have checked Network Sharing is enabled, it can ping/browse the machines which are not showing up, it is on the correct range and is using the correct DNS, DHCP, and Gateway. I have tried setting these details to static and it is the same.
It is running Windows 10 (as are all the client PCs) so we have tried the network reset option. And finally a system restore.
I still cannot see the other machines in this tab. We have recently started looking after this client and one of the things I have looked at is that they use a proxy server. This is configured and sent out to the machine under group policy. The policy has applied when I run a gpresult /r and the internet connects fine. I did notice when I dialled in and looked under Ethernet on the W10 network settings that it said action needed under the adapter. It needed the user credentials for the proxy. I entered these and it returned to say connected. I have not had this since after several reboots and the above troubleshooting steps.
Any help would be appreciated.
