I started getting this error after I demoted one domain controller and added a new one on the network. After researching quite a bit, I found out that some of the _msdcs/DC, GC, PDC records in the DNS server still had entries for the old domain controller. I deleted all the records of the old Domain Controller and the warning disappeared.
Make sure that UDP port 123, used by the Network Time Protocol is opened between the time server and the computer reporting the error.
The time services has not been able to connect to a time source. If a time source is configured check the connectivity between the computer reporting the error and the time server.
As per Microsoft: This issue can occur because of repeated network issues or if the Time service has been unable to find a domain controller to synchronize with for a long time. To reduce network traffic, the Time service will wait 960 minutes before it tries again, and no synchronization takes place during this interval, even if network connectivity is restored after being in a disconnected state for an amount of time that is less than the synchronization interval.
