 When booting up a Windows VM post failover, if you receive an unexpected shutdown message on the recovered VM, it indicates that a VM shutdown state wasn't captured in the recovery point used for failover. This happens when you recover to a point when the VM hadn't been fully shut down.

 After you fail over your virtual machines to Azure, you can fail back the virtual machines to the on-premises site. To fail back, you need to reprotect the virtual machine from Azure to the on-premises site. For this process, you need an on-premises master target server to receive the traffic.
 
 If your protected virtual machine is a Windows virtual machine, then you need a Windows master target. For a Linux virtual machine, you need a Linux master target. Read the following steps to learn how to create and install a Linux master target.
