Azure network error 1233, error 53 path not found
If you have an Azure VM that is suddenly getting errors including
- Error 53: The network path was not found
- Error 1233: The network location cannot be reached
- Server can’t be pinged but can ping out
After ensuring that the firewall settings are ok (or if you know 100% this was working and now after a restart of the VM it is not… then check Device Manager, from the View menu ensure that Show Hidden Device is ticked. Expand Network Adapters and confirm that there are no hidden and unused Hyper-V network adapters
The module used was obtained from TechNet but for simplicity I have included it in the download below along with a wrapper script to call the required cmdlet. Before running the script open a PowerShell session with Run As Administrator and call
Set-ExecutionPolicy RemoteSigned
to allow the script to be used. The download can be unzipped on your server in any location and then you can right-click on the file Remove-AllHiddenHyperVNIC.ps1 and choose Run with PowerShell. It will remove all hidden Hyper-V NICs from the server.
After that reboot the machine and access will be fully restored
*** As always the script is provided on an as is basis, please test it before you use it in a production environment. ***
