Use the tool to troubleshoot OS-level issues and to collect advanced logs and configuration files for further analysis. The following are some common issues that EC2Rescue can address:Instance connectivity issues due to firewall, Remote Desktop Protocol (RDP), or network interface configuration.OS boot issues due to a blue screen or stop error, a boot loop, or a corrupted registry.Any issues that might need advanced log analysis and troubleshooting.Note: You can capture a screenshot of an Amazon EC2 Windows instance to determine the state of the instance.You can run EC2Rescue manually or automatically using the AWS Systems Manager AWSSupport-ExecuteEC2Rescue Automation document.System requirementsEC2Rescue requires an Amazon EC2 Windows instance that:Runs on Windows Server 2008 R2 or laterHas .NET Framework 3.5 SPI or later installedIs accessible from an RDP connectionNote: EC2Rescue runs only on Windows Server 2008 R2 or later, but the tool can analyze the offline volumes of Windows Server 2008 or later.ResolutionFirst, choose whether you want to use the Systems Manager AWSSupport-ExecuteEC2Rescue Automation document, or run EC2Rescue manually. Then, follow the steps below for your chosen method.Use the Systems Manager AWSSupport-ExecuteEC2Rescue Automation documentThe AWSSupport-ExecuteEC2Rescue Automation document combines AWS Lambda functions with Systems Manager and AWS CloudFormation actions to automate EC2Rescue steps. For more information about how the document works, permissions requirements, and prerequisites for using the tool, see Run the EC2Rescue tool on unreachable instances.Important: The Automation workflow stops the instance. If the instance has an instance store volume, any data on the volume is lost when the instance stops. If you’re not using an Elastic IP address, the public IP address releases when the instance stops.When you're ready, run the Systems Manager AWSSupport-ExecuteEC2Rescue Automation.Run EC2Rescue manuallyYou can run EC2Rescue manually using one of the following methods:Use EC2Rescue for Windows Server GUI.Use the EC2Rescue for Windows Server command line interface (CLI).Use the AWSSupport-RunEC2RescueForWindowsTool Systems Manager Run Command.First, download EC2Rescue on your Amazon EC2 Windows instance.Note: The AWSSupport-RunEC2RescueForWindowsTool Systems Manager Run Command document method downloads and verifies EC2Rescue for Windows Server for you.Then, use EC2Rescue to troubleshoot Amazon EC2 Windows Server instance issues:Instance connectivity issues: Use the Diagnose and Rescue feature in Offline instance mode.OS boot issues: Use the Restore feature in Offline instance mode.Advanced logs and troubleshooting: Use the Capture logs feature in either Current instance mode or Offline instance mode.Current instance modeThis mode analyzes the instance that EC2Rescue is currently running.

EC2Rescue analyzes the volume and presents automated rescue and restore options. Offline instance mode also includes the same Capture logs feature as Current instance mode.FeaturesSystem Information: Displays important system information about the current system in a text box for easy copying.Select Disk: If multiple offline root volumes are connected to the instance, this feature allows you to select a specific volume.Note: If the selected disk isn’t already online, this feature automatically brings the disk online for you.Diagnose and Rescue: Detects and provides options to automatically fix common configuration issues that prevent RDP connections or that cause instance status checks to fail. The following items are inspected for possible configuration issues:System time settingsWindows Firewall settingsRemote Desktop settingsEC2Config version and settings (Windows Server 2012 R2 and earlier)EC2Launch version and settings (Windows Server 2016 and later)Network interface settingsRestore: Set the offline instance to boot to Last Known Good Configuration or Restore registry from backup.
