| Event Information | The W32tm command is used to test and maintain time synchronization between workstations and servers in an enterprise. If you use the command on a Windows 2000 domain controller, you may receive an error message in the output of the command if you are using the -v switch for verbose output and\or this error message may be logged in the System Event log: CAUSE: This problem can occur on a domain controller (DC) when the default port (123) is already in use by the Time service that is running on the DC before the command is executed. The W32tm command tries to start the Time service before execution, but it does work if the service is already started. RESOLUTION: To resolve this problem, note that the following command switches for W32tm execute successfully: -tz -adj -adjoff -s To successfully use the W32tm command on a DC with the other options, use one or more of the following steps: Stop the Time service to execute the command, and then restart the service. Change the port by using the -p switch to execute the W32tm command on a DC. |
