Symantec Network Boot Service (TFTP) won't start on NBS Site Server

Products

• Client Management Suite
• IT Management Suite

Issue/Introduction

Summary: The PXE boot process initiates successfully and the client acquires an IP address from the Site Server. However, the process fails during the TFTP phase.

Investigation: An inspection of the Site Server revealed that while the Symantec Network Boot Service (TFTP) is configured to start automatically, it was found in a stopped state. Attempting to manually restart the service resulted in it starting and immediately crashing/terminating.

Environment

DS 8.x

Cause

"Windows error code 10049" indicates a network socket issue. It typically means an application or service tried to bind to an IP address that doesn’t exist on your computer, or an invalid address/port was assigned.

During installation of NBS, the TFTP service binds to a specific IP address. If the IP address of the NBS server changes after installation, this could result in the TFTP server not starting.

Resolution

Resolution Steps:

1. If you know the original static IP address before it changed then set the Site Server back to that original IP address
2. If you do not know the original IP address then uninstall and reinstall NBS:
   1. From the Notification Server, cd to: <install drive>:\Program Files\Altiris\Notification Server\NSCap\bin\Win64\x64\Deployment\SBS
   2. Copy the Symantec_DeploymentSolutionsSBS_8_6_x64.msi to the Site Server
   3. To uninstall enter: msiexec /x Symantec_DeploymentSolutionSBS_x64.msi
   4. To reinstall enter: msiexec /i Symantec_DeploymentSolutionSBS_x64.msi skipaim=1
   5. Send Basic Inventory from the Symantec Management Agent on the Site Server
   6. Run 'Resource Membership Update' ( delta and policy ) from the SMP Console at Settings > Notification Server > Resource Membership Update
   7. Rebuild the reboot configuration
