Q. Why do I receive time errors when I run the Dcdiag utility?

A. The time errors might be occurring because the domain controller (DC) isn't configured with an external time source. You can check the DC's time-forwarding status by running the command

net time /querysntp

If the DC isn't set to query an external Simple Network Time Protocol (SNTP) server or the configured server isn't available, you can set a valid time value by running the command

net time /setsntp:<ip address/dns server>
