NotDeletable Metabase Property (IIS 6.0)
This property is not valid in IIS 6.0. In earlier versions of IIS, the NotDeletable property indicates whether a server can be deleted by using IIS Manager. If this property is set to true, an attempt to delete the affected server instance using IIS Manager results in an error.
You can configure this property at the following locations in the IIS metabase.
