Access to shared printers/Folders suddenly stops

P/s can anyone assist on this. Suddenly, I can not access my shared printers and folders again. Instead when I type network path \\192.168.1.x so that it can list shared resources on the computer for me to connect. I get the message "you might not have permission to use this network resource. contact administrator of this server to have access permissions"
The network is not present or not started.

Again I have run the windows network tools over and over again, joining computers to workgroups etc. shared resources incluiding printers allows for some hours then stops.

Thank you all.
