Application Note #011

Windows Time Service

1.  Open Settings->Control Panel->Windows Tools->Services and ensure that the Windows Time-Service's Startup Type is set to Automatic and that the services are running.

    

Note:

For Windows 11, Microsoft renamed Administrative Tools to Windows Tools meaning you might find the Windows Time Service on systems older than Windows 11 under:

Settings->Control Panel->Administrative Tools->Services

Edit the Registry to enable NTP

2. Open the Windows Registry

3. Under the windows registry got to:

 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProviders\NtpServer

4. Right click on “Enabled” and change the “Value Data” from 0 to 1 and click OK

5. Under Settings->Control Panel->Windows Tools->Services

• Stop and Restart “Windows Time”

Note:  

Please check if your computer is reachable through the network. You may have to change the Windows Firewall settings to allow inbound/Outbound UDP port 123.

6. Once the steps above have been completed verify on the CS141 that the time services are working properly under System- Date & Time
