Hyper-V error 0x8009030E occurs during an authentication failure when attempting to establish a connection between the Hyper-V host and the virtual machine. This is often associated with incorrect or mismatched security credentials.

Below, we walk you through the different solutions you can try to resolve the forever error. However, before proceeding, we recommend that you thoroughly verify the credentials you are using to establish a connection with the Hyper-V host. This precautionary measure ensures that the error is not arising from incorrect or mismatched credentials on your end.

1. Run Hyper-V Manager as an administrator

Many operations in Hyper-V, such as modifying settings, creating virtual networks, or accessing configuration options, require administrative access to tools. In some cases, encountering error 0x8009030E may indicate that you lack the required privileges.

This is why, we recommend starting the troubleshooting by making sure that you have the proper permissions required to perform the targeted task.

If you’re currently using a standard account (Standard vs. Administrator Windows Account), you can do this by first logging into Windows as an administrator. After boot, right-click on the Hyper-V Manager shortcut and choose Run as administrator from the context menu.

Confirm your action in the User Account Control prompt and check if the problem is resolved.

2. Set up Kerberos delegation

If the lack of administrative access wasn’t causing the problem, our next course of action would be to address authentication-related issues.

For this, we will configure Kerberos delegation, which is a feature that allows programs on behalf of the client to use the client’s security credentials. If the correct Kerberos Constrained Delegation is absent, it can lead to a number of authentication errors such as the one at hand.

In this method, we’ll first access a list of all the services and resources to which the computer account is allowed to delegate credentials. If the relevant services for Hyper-V are not included in the output section, it would mean that Kerberos delegation may be missing or not configured properly.

In that case, we’ll proceed to enable and configure it, before testing the connection again.

This command will display a list of services or resources to which the selected account is allowed to delegate credentials. Review the output to see whether services related to Hyper-V are included. If it doesn’t include those services, Kerberos Delegation is likely missing or improperly configured.

3. Change Account Options

You may also face the issue if the ‘Account is sensitive and cannot be delegated’ option is enabled in the properties of the target account.

4. Check Firewall and Antivirus Settings

Firewalls and antivirus programs are known to potentially disrupt communication between various components and services, and this may also be the case with the Hyper-V error you are experiencing.

To resolve this issue, it is important to review the configuration of your firewall and antivirus software. These programs can block essential network traffic that is required for proper authentication and communication between the Hyper-V host and other components.

However, it’s important to note that the specific steps for checking these settings will vary depending on the security program you’re using. You can refer to the official documentation provided by the developer, or contact the official team for assistance.

If you can’t locate these settings, you can try temporarily disabling Windows protection and then performing the action that was triggering the error initially. If the problem does not appear after disabling the protection program, consider whitelisting Hyper-V and its components in the application to avoid such problems in the future.

5. Update Hyper-V Integration Components

Integration components are a set of drivers and services that help establish seamless communication and functionality between virtual machines (VMs) and Hyper-V hosts.

It is worth updating these services to make sure they are working properly and are not contributing to the problem.
