4.2 All_ClockSynchronization

Use this Knowledge Script to monitor the synchronization of clocks for one or more Domain Controllers. This script raises an event if the number of seconds of difference between clocks exceeds the threshold you set.

This script is a member of the Exchange2007 recommended Knowledge Script Group. For more information, see Section 4.43, Recommended Knowledge Script Group.

4.2.1 Resource Object

Exchange_Server

4.2.2 Default Schedule

By default, this script runs every 15 minutes.

4.2.3 Setting Parameter Values

Set the following parameters as needed:

Parameter	How to Set It
General Settings
Job failure event notification
Event severity when job fails	Set the severity level, from 1 to 40, to indicate the importance of an event in which the All_ClockSynchronization job fails. The default is 5.
Monitor Clock Synchronization with Domain Controller
Comma-separated list of Domain Controllers to test	Use this parameter to limit the number of Domain Controller (DC) clocks that are tested for synchronization with the clock on the server running the ClockSynchronization Knowledge Script. Provide a list of fully qualified hostnames, separating multiple names by commas. Leave this parameter blank to test all DC clocks in your organization.
Event Notification
Raise event if clocks are not synchronized?	Select Yes to raise an event if the clock on the server running the ClockSynchronization Knowledge Script is not synchronized with the clock on the DC. The default is Yes.
Threshold - Maximum clock difference	Set the maximum number of seconds that the server clock can be out of sync with the DC. For example, setting the threshold to 2 indicates that it is acceptable for the clock to be two seconds faster or slower than the clock on the DC. The default is 10 seconds. If you want the server clock to be in sync with the DC clock, set this parameter to 0.
Event severity when clock difference exceeds threshold	Set the severity level, from 1 to 40, to indicate the importance of an event in which the clock synchronization offset exceeds the threshold you set. The default is 25.
