How to fix system error 67

To fix the "System error 67 has occurred. The network name cannot be found" error when connecting to Azure storage, consider the following solutions:

1. Check Port 445: Ensure that outbound communication to Azure Files datacenter on port 445 is not blocked. You can use tools like Test-NetConnection cmdlet or AzFileDiagnostics to verify if port 445 is accessible.
2. Validate Permissions: Ensure that share-level permissions for the Azure file share are configured correctly. This includes checking if the account you are using has the necessary permissions to access the share.
3. Network Configuration: Verify that your network configuration allows for proper connectivity to Azure services. This may involve checking firewall settings or any network policies that might restrict access.
4. Restart Services: Sometimes, restarting the relevant services on your local machine or the Azure service can resolve connectivity issues.

By following these steps, you should be able to resolve the error and establish a connection to your Azure storage.

Hi @MNBB Admin,

Welcome to Microsoft Q&A Platform.

Can you please confirm from where you are trying to connect to Azure Storage? Also, please provide the detailed error screenshot and any additional information in a private message.

In most cases, the issue occurs due to SMB port 445 being blocked or an incorrect storage account or share name.

Check if port 445 is blocked by Run the following command:

Test-NetConnection -ComputerName storageaccount.file.core.windows.net -Port 445

If the result shows:

TcpTestSucceeded : False

It means your ISP, firewall, or company network is blocking port 445, which prevents mounting Azure File Shares.

If you are trying to mount an Azure File Share to a local machine and encounter this error, the antivirus software may sometimes block the connection. Please uninstall the antivirus and try again, Refer: System error 67 has occurred for more details.

Try connecting from a different network (for example, a mobile hotspot) to confirm whether the issue is network related.

Refer the "System error 67 has occurred. The network name cannot be found" error message and System error 67 has occurred
