Network discovery and File sharing will not turn on and stay on, this
has not been a problem until recently. I have checked that all
dependency services have started correctly and that it is allowed
through the windows firewall, it means I cannot access
my home group and therefore any files on other computers
Method 1
Check if below conditions are met-a) All computers should be in the same workgroup for computer browsing to function properly.
b) Make sure that computer is on and that you've enabled file and printer sharing on your network.
c) If you encounter difficulties accessing computers that are visible in Network Neighborhood, make sure the computer being accessed has an account with the same name/password as the system connecting to it.
Method 2
Check the Services. Ensure that the required services are started on all the computers:Go to Start\Control Panel\ Administrative Tools\ Services.
o Computer Browser
o DHCP Client
o DNS Client
o Network Connections
o Network Location Awareness
o Remote Procedure Call (RPC)
o Server
o TCP/IP NetBIOS helper
o Workstation
All of these services should be started, and their startup type should be automatic.
To change the startup type, double-click on the service name and change accordingly.
