PROBLEM
For feature classes participating in a geometric network or network dataset, the Delete and Rename options are disabled in the context menu and the feature classes cannot be modified or removed.
This is expected behavior. The management of network feature classes is more restrictive as opposed to managing simple feature classes. While a network feature class alias can be changed, its name cannot. Deleting a network feature class is also more difficult compared to deleting simple feature classes.
