It is usually because the GPService on the server computer is not running and it needs to be restarted.
To fix this go to the Server Machine (you require administrator privileges)
On the server machine click on the Start button and type “services” and then hit enter which should open the Microsoft Services Consul.
The Microsoft Services Console will then be displayed.
Scroll down to the row GPService.
Right click on this row to bring up the submenu.
Select Start or Restart from the menu
