What is the purpose of nesting Hyper-V clusters inside each other? Nested virtualization may be extremely tricky, especially in the networking part. Also, Hyper-V is not the best option for that kind of configuration.

Microsoft Failover Cluster requires a working DNS service to validate and work properly. According to the screenshots you have provided, your DNS servers are located in different subnets (10.x and 100.x) and are not accessible by your cluster nodes (0.x and 1.x). Fix that problem, and your cluster should validate correctly.

You can try this as a workaround:

Registry setting to enable or disable the hardening changes

During the timeline phases in which you can enable or disable the hardening changes for CVE-2021-26414, you can use the following registry key:

Path : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole\AppCompat

Value Name: "RequireIntegrityActivationAuthenticationLevel"

Type: dword

Value Data: default = 0x00000000 means disabled. 0x00000001 means enabled. If this value is not defined, it will default to enabled.

Note You must enter Value Data in hexadecimal format.

Important You must restart your device after setting this registry key for it to take effect.

  • Something else you may want to look into is updating your client machine and if there are no updates applicable e.g., Enterprise LTSC 2019 you will then need to do an in-place upgrade to LTSC 2021.
