The config.xml is configured correctly per the documentation, but the MID Server fails to register with the instance. Symptoms The MID Server service appears to start on the Windows 11 host, but the MID Server record does not appear in the MID Server [ecc_agent] table on the ServiceNow instance.No MID Server entry is created or visible in the instance after completing the manual installation steps. Facts The installation steps were followed according to the ServiceNow documentation: Manually Install a MID Server on Windows.The config.xml file was configured as instructed.The host operating system is Windows 11.ServiceNow requires that MID Server host systems satisfy the documented MID Server System Requirements before installation is attempted. Supported Windows operating systems for MID Server installation: Supported OSWindows Server 2012Windows Server 2016Windows Server 2019Windows Server 2022Windows Server 2025 Note: The above applies to environments where the MID Server must be installed on a Windows server to discover Windows-based servers, run Service Mapping patterns, or execute Orchestration commands on Windows devices. Virtual machines and 64-bit systems are supported. Reference: MID Server Installation Prerequisites Cause Windows 11 is not a supported operating system for MID Server installation. ServiceNow only supports Windows Server editions (2012, 2016, 2019, 2022, and 2025) as MID Server host operating systems. Installing the MID Server on an unsupported OS will prevent the MID Server from registering with the instance. Solution Migrate the MID Server installation to a supported Windows Server operating system. Identify a host running one of the supported Windows Server operating systems listed in the Facts section above.Verify that the new host meets all MID Server system requirements as documented in the MID Server Installation Prerequisites.Transfer the existing config.xml from the Windows 11 host to the new supported host, updating any host-specific parameters (e.g., hostname, IP address) as needed.Install the MID Server on the supported host following the ServiceNow documentation: Manually Install a MID Server on Windows.Confirm that the MID Server record appears and reaches Up status in the MID Server [ecc_agent] table on the instance.Decommission the MID Server installation from the Windows 11 host.
