SYMPTOMS
Domain controllers may display the following event 54 and 64 errors in the system event log:

Event Type: Warning

Event Source: w32time

Event Category: None

Event ID: 54

Date: date

Time: time

User: N/A

Computer: ROOTDC

Description: The Windows Time Service was not able to find a Domain Controller. A time and date update was not possible.

Event Type: Warning

Event Source: w32time

Event Category: None

Event ID: 64

Date: date

Time: time

User: N/A

Computer: ROOTDC

Description:



CAUSE
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.



MORE INFORMATION
Accumulated time errors may cause certain network operations to fail. To update the Time service and let it know that network connectivity has been restored and that it should resynchronize, use any of the following commands at a command prompt:

'''net stop w32time

w32tm -s

net start w32time'''

NOTE Because the Forest Root DC is the timesource for the whole forest, it has to be configured manually to synchronize time with an external time source. Also, if time synchronization with an Internet source isn't critical, you can also configure the DC with the PDC master role to be the authoritative time server.

NOTE: You can safely ignore the Event log entries that are listed in the &quot;Symptoms&quot; section of this article if you do not want to synchronize the Forest Root DC with an external timesource. However, if you want to disable the these events, set the Type value to NoSync as described in the following Microsoft Knowledge Base articles:
