Unable to Update Time Using Network Time Protocol (NTP)

NOTE: For smart card authentication to work, the devices must have the clocks synchronized with the domain against which the users with the smart cards are authenticated.

Affected products

This issue was first seen on several X945 MFPs, however, it is possible this issue may be seen on printers with similar firmware architecture.

Preliminary checks

• Make sure the devices in question are configured to use NTP.
• Determine if NTP implementation on certain devices is different from other devices.
• Make sure these devices all have the same NTP server address.
  Note: This address may be the address of one of the Windows AD domain controllers. This may even be the same domain controller the users are authenticating against with the smart cards.
• Verify any network routing changes have may have taken place.

Suggested remedy

If all preliminary checks have been performed, then capture anetwork trace to locate NTP traffic generated and received by the device and escalate this issue to Lexmark Technical Support.

One instance was determined to be the 'Stratum' level reply from the NTP server which exceeded the Stratum' level that is expected. This resulted in a firmware change to our NTP implementation to only log a warning instead of an error.
