MECM Client Windows Updates Scan Failed with Error = 0x80244022

Today, I was informed by a customer regarding an MECM (Microsoft Endpoint Configuration Manager) updates deployment issue. Some machines haven't downloaded updates for months.

Configure Azure Bastion to Connect to Virtual Machines

Azure Bastion is a service (PaaS) which provides the ability to connect (RDP/SSH) to Azure virtual machines directly over TLS. With Azure Bastion, you don’t need to configure a public IP address on the VM to connect through RDP or SSH. Also, you don’t need any additional agent or software installed on your machine or inside Azure VM since you connect to VM directly from the Azure portal. Only an HTML5 capable browser is sufficient.

Azure Bastion deployment is per virtual network. Therefore, once you deployed it to a virtual network, you can connect to any VM inside that virtual network.
