Have not been able to get automatic IP on LAN because DHCP won't start .
The error message when trying to restart DHCP is :
"Windows was unable to restart DHCP Client service . Error 5 : Access...

Just as suddenly as it stopped working , it has started functioning again . I didn't reboot so maybe some process was blocking it .
So problem apparently solved .

Although the time and date can be seen on the taskbar , when I click to see the full calendar , nothing comes up at all . My Windows 10 installation is up to date .
Thanks,
Alan
