CONFIGMGR ERROR OBJECT: INSTANCE OF SMS_EXTENDEDSTATUS
I have seen many blog posts that talk about integration with MDT etc. for this error.
I have seen this error occur when attempting to edit a task sequence in ConfigMgr.
Copy the TS works fine and editing it.
To fix being able to edit the offending TS just restart the winmgmt service on the ConfigMgr server you are trying to edit the TS on, close the console and reopen it then edit the TS again.
