Problem Description:

A client encountered a deployment failure when using an Instant Task to deploy an OS image over the network.

The error displayed: Invalid authentication passcode.

1. 
   

Observations:

• The authentication passcode has been verified as correct.
  

• Valid username and password credentials are used.

• The same OS image deploys successfully when using a Standalone Task, confirming that the image itself is not corrupted or misconfigured.
  

Impact:

• Deployment fails for machines using Instant Task with misaligned Remote Office boot media.
  

Root Cause:

• The issue occurs due to a mismatch between:
  

  1. The Remote Office of the boot media used to start the target machine

  2. The Remote Office assigned to the Instant Task

• OS images are created in a specific Remote Office and may be replicated to others.

• Only the image-created Remote Office and its replicated Remote Offices are valid for the Instant Task.

• Booting the target machine using media from a different Remote Office than the task-assigned Remote Office triggers the authentication error.
  

Solution:

1. Verify Remote Office Alignment
   

   • Ensure the Remote Office of the boot media matches the Remote Office assigned to the Instant Task.

2. Confirm Booted Remote Office on Target Machine

   • Verify the Remote Office displayed in the top-right corner of the deployment screen matches the task’s assigned Remote Office.
     

Resolution / Expected Outcome:

• Once the boot media Remote Office and the task Remote Office are aligned, the “Invalid authentication passcode” error is resolved.

• The OS deployment via Instant Task completes successfully.
