Answer 3

Hello Yasila,

Greetings! Welcome to Microsoft Q&A Platform.

I understand that you are having issues with mounting your file share where you get the error: “System error 67 has occurred. The network name cannot be found” usually occurs when the network path is not found, or the network name is incorrect.

System error 67 can also occur if port 445 outbound communication to an Azure Files datacenter is blocked. I would suggest you go through this document regarding solving Port 445 blocked error, also refer this troubleshooting doc.

To see the summary of ISPs that allow or disallow access from port 445, go to TechNet.

To check if your firewall or ISP is blocking port 445, use the AzFileDiagnostics tool or Test-NetConnection cmdlet.

To troubleshoot this issue, you can try the following steps: Verify that the network path is correct, and that Azure File Share exists. You can do this by navigating to the Azure portal and checking the storage account and file share.

Ensure that the correct credentials are being used to access the Azure File Share. You can try using the storage account name and key to authenticate the connection.

Check if the SMB protocol version, authentication, and encryption settings are configured properly. You can refer to the following link for more information on SMB security settings: https://docs.microsoft.com/en-us/azure/storage/files/storage-files-smb-security.

Ensure that the firewall settings are configured properly to allow traffic to and from the Azure File Share. You can refer to the following link for more information on firewall settings: https://docs.microsoft.com/en-us/azure/storage/files/storage-files-networking-overview,https://learn.microsoft.com/en-us/azure/storage/file-sync/file-sync-networking-overview.

Hope this answer helps! Please let us know if you have any further queries. I’m happy to assist you further.
