I'm worried that one of our SDE Geodatabases may now be corrupted! The steward of that database was deleting a feature dataset when ArcCatalog hung. After waiting 15 minutes he stopped and restarted ArcCatalog. When he reconnected all that he was trying to delete was gone except for one feature class, but what is really weird is that the feature class was one of several under the feature dataset. The feature dataset is now gone but the lone feature class is now showing up in the root and there appears to be no way to delete this feature class. ArcCatalog just hangs when trying to delete this feature class. Any ideas?
