OS Deployment - Knowledge base

Unexpected network error occurred

Problem

You can see the error message "Unexpected network error occurred" on the screen when you try to do the following:

  • During image creation
  • During deployment

 Cause

  1. When a Antivirus software / Windows firewall is blocking the file path or file transfer.
  2. When a image file has reached the size limit of 4 GB and is saved in FAT32 file system.
  3. When the network connection is interuppted in the imaging machine or the image repository machine or the target computer where you are performing deployment.

Resolution

To resolve this problem, follow the steps given below:

Verify Antivirus/Firewall block

Go to the image repository machine. Check if any firewall/ antivirus is blocking the share path. If it is blocking, exempt the network share folder from firewall/antivirus blockage and proceed with image creation/deployment.

Ensure that the network share drive is in NTFS File system instead of FAT32

Based on the OS image the file size can go beyond 4GB. Hence ensure that it is formatted with NTFS file system. If the format is in FAT32 file system, large files of more than 4 GB size cannot be saved as a single file.

Resolve network connection

  1. If the network connection has recovered from the error automatically, retry image creation. Deployment will get retried automatically on the target computer. 
  2. If the network connection hasn't recovered for while, check the connection & "Retry" image creation/ deployment. If it still doesn't work, create a new image and proceed with deployment.
