Why do I receive System Event IDs 54 and 64 in the System log?

A. System Event IDs 54 and 64 will appear in your System log if the server's time service can't find a domain controller (DC) to synchronize time with. To limit the amount of traffic on the network, the DC attempts this synchronization only every 960 minutes (16 hours), even if the connection between the server and DC is restored during that time.

To force the server and DC to resynchronize the time, go to the command prompt and execute one of the following sets of commands:

  • net stop w32time
    net start w32time
  • w32tm -s (/resync in Microsoft .NET)

If the server is the forest root DC, you'll need to configure it to synchronize the time with an external source.
