Hi Rasitha Mudugama Hewage

Just checking in to see if you had a chance to review the response provided to your question.

Use an internal NTP source (recommended in enterprise). Example:

Primary Time Server: ntp.corp.local

On the node itself, test:

w32tm /stripchart /computer:time.windows.com /dataonly /samples:3

If it fails -> UDP/123 is blocked, or DNS is wrong.

Or try setting:

pool.ntp.org

• Or even the IP address of the NTP server (instead of FQDN).

Example:

Primary NTP server: 216.239.35.0 (one of Google’s NTP IPs)

Feel free to reach out if you have any further queries.

Hi Everyone,

Thanks for your support and connected node to azure arc but when i try to create azure local and see this message. " not validated"

Answer 3

Go back one step in the wizard (click Back) until you see the Time settings or NTP settings page.

1. In the field PrimaryTimeServer, enter a valid NTP server. You can use either:
   • A public NTP server:
   • time.windows.com
   • pool.ntp.org
   • Or your own internal NTP server if your company uses one (example: 10.1.10.20).
2. Save and move forward again to Review and apply.
3. The validation error should disappear once the PrimaryTimeServer field is filled correctly.

Azure Arc requires the local server’s clock to be synced. If time drifts, certificates and authentication will fail. That’s why the wizard won’t let you continue without a valid time source.
