+====== Fixing the "red arrow" problem in component services or error 80070422 ======
+===== Intro =====
+This is about an error I've got in a Windows 2012 server: in the "Component services" funcion (COM+), when opening the "com+ applications" a red arrow appears:
+{{ :windows:20151223_com_1.png |}}
+And when trying to open the "COM+ Applications" folder, the following error is displayed:
+<WRAP center round alert 60%>
+An error occurred while processing the last operation.
+Error code 80070422 - The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
+The event log may contain additional troubleshooting information.
+</WRAP>
+===== Resolution =====

+[[http://blogs.msdn.com/b/asiatech/archive/2012/01/25/how-to-troubleshoot-the-red-arrow-issue-in-component-services-iii.aspx|here]] for instance, I've discovered what was going on in my particular case:
+**some services have to be started**.
+In particular those services that must be configured to run automatically are "COM+ System Application" and "Distributed Transaction Coordinator".
