You have an Azure virtual machine named VM1 that runs Windows Server. The operating system on VM1 fails to fully initialize its network stack, and you cannot establish a network connection. You need…

Azure Bastion relies on network connectivity to establish a secure RDP/SSH connection to the VM, which would not be possible if the VM's network stack has failed.

The Azure Serial Console provides access to a text-based console, which operates independently of the VM's network or operating system state, allowing administrators to troubleshoot network configuration issues or other boot-related problems, even when the network stack is not functional.

Just-in-time (JIT) VM access is a security feature that opens network ports for a limited time to allow inbound access, but it still requires the VM's network stack to be functional to establish the connection.
