It appears whenever an application doesn’t have the required permission to start DCOM server with the help of DCOM infrastructure. You’ll have to determine whether some Registry keys need access, read, write permissions or there are corrupted Registry entries. There are other possibilities too. Your DCOM settings might have recently changed, or administrative permissions are needed to access runtime broker DCOM settings. If your computer is grappling with issues like this, it’s better to clean it thoroughly using an efficient cleaning utility such as the ST Cleaner software.
