If you’re too facing this error, you need to find out how this issue can be solved. If your system is a part of domain, you need to ask domain controller to get support on this. And if you’re facing this problem on a isolated machine (non-domain system), you need to unplug the network cable from the machine. After unplugging cable, turn off WiFi and reboot the machine. After restarting the machine, plug the network cable, and turn on WiFi. In most of cases, this will solve the problem.
