I have a SP 2010 Content Type that just clings for its dear life. It inherits from "Form" and any associated workflows and lists have been deleted. Site & Site Collection recycle bins have been emptied. The SharePoint object model does not recognize any associated objects (used SP Manager and PowerShell separately). I did find list associations lingering in the Content DB however, those lists are of the aforementioned deletes. So it's really a matter of 1st taking care of the "phantom lists" menace, but my hands seemed tied using the SharePoint API. And I'm obviously not going to run SQL DELETES on a bunch of tables in the Content DB, unless I'm pining for SharePoint suicide. I've Googled to my wit's end. Most pages point to the recycling bin issue, but as I mentioned, I've taken care of that already. I'd be most appreciative and in awe if someone had a safe, sure-fire method to extricate this tenacious tyrant of a Content Type.
I also ran stsadm
-o databaserepair -url https://www.com -databasename DB_NAME -deletecorruption to no avail.
And I tried stsadm
-o forcedeletelist but got a 0x80070002 which i'd say is due to the problems stated in my main entry.
I'd like to hope that there's someone out there that could crack this one. I can't be the only one to have ever encountered this.
