    The error you are encountering during the WSUS post-installation, specifically the "HTTP status 400: Bad Request," indicates that there may be an issue with the request being sent to the DssAuth WebService. This can occur due to various reasons, such as misconfiguration or issues with the service itself.

    To troubleshoot this issue, consider the following steps:

    1. Check WSUS Configuration: Ensure that WSUS is properly configured and that all necessary services are running.
    2. Review Event Logs: Look at the Windows Event Logs for any additional error messages that might provide more context about the failure.
    3. Network Connectivity: Verify that there are no network issues preventing the WSUS server from communicating with other required services.
    4. Permissions: Ensure that the account running the WSUS service has the necessary permissions to access the DssAuth WebService.

    If the problem persists, you may need to consult the WSUS documentation or seek further assistance from Microsoft support.
