These 10016 events are recorded when Microsoft components try to access DCOM components without the required permissions. In this case, this behavior is expected and by design.
A coding pattern has been implemented where the code first tries to access the DCOM components with one set of parameters. If the first attempt is unsuccessful, it tries again with another set of parameters. The reason why it doesn't skip the first attempt is because there are scenarios where it can succeed. In those scenarios, it's preferable.
These events can be safely ignored because they don't adversely affect functionality and are by design. It's the recommend action for these events.
