Based on the error message indicating an issue with querying the DNS server, two critical network-related configurations must be verified to successfully deploy an SMB volume in Azure NetApp Files:

VNet Configuration:Ensure that the Azure NetApp Files volume and the Active Directory Domain Services (AD DS) are configured within the same Virtual Network (VNet). This is crucial as it ensures that the volume can communicate effectively with the AD DS, which is necessary for SMB authentication and service location.

Network Security Group (NSG) Settings:Verify that the Network Security Groups associated with the subnet or the VNet where the Azure NetApp Files volume is deployed allows DNS traffic. Specifically, inbound and outbound rules should permit traffic over the ports typically used by DNS (usually TCP/UDP 53). This allows the volume to successfully resolve DNS queries which are essential for integrating with AD DS.

These two checks are aimed at resolving connectivity and DNS resolution issues that are likely causing the deployment to fail. For more detailed troubleshooting and setup instructions, please refer to Azure's official documentation on Network Security Groups and VNet configurations:Azure Networking Documentation.
