I have checked the dns connectivity from Azure stack hci Nodes to dns server's and itseems fine.

Type 'ValidateNetwork' of Role 'EnvironmentValidator' raised an exception: { "ExceptionType": "json", "ErrorMessage": { "Message": "Network requirements not met. Review output and remediate.", "Results": [ { "Name": "AzStackHci_Network_Test_Infra_IP_Connection_DNS_Server_Port_53", "DisplayName": "Test DNS server port connection for all IP in infra IP pool", "Tags": { }, "Title": "Test DNS server port connection for all IP in infra IP pool", "Status": 1, "Severity": 2, "Description": "Test DNS server port connection for all IP in infra IP pool",

Hi Mohd Shahed,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

To resolve the Azure Stack HCI validation issue, you may need to configure nested virtualization and enable MAC Address Spoofing for the virtual machine(s) in question.

Make sure that port 53 (UDP and TCP) is open and accessible between all Azure Stack HCI nodes and the DNS servers. Use the following command to validate connectivity:

Test-NetConnection -ComputerName <DNS_Server_IP> -Port 53

Steps to Configure:

Enable Nested Virtualization: Use the following PowerShell command to expose virtualization extensions:

Set-VMProcessor -VMName <VM_Name> -ExposeVirtualizationExtensions $true

Enable MAC Address Spoofing: In some scenarios, MAC Address Spoofing must be enabled to pass DNS validation. Use the following command:

Set-VMNetworkAdapter -VMName <VM_Name> -MacAddressSpoofing On

This allows the VM to modify its MAC address and ensures proper packet handling in advanced network configurations.

After configuring these settings, rerun the Azure Stack HCI validation process and verify if the issue is resolved.
