Remove Exchange Virtual Server cannot be performed because the corresponding Exchange Virtual Server objects in Active Directory have not been found.  If you have not previously removed this Exchange Virtual Server, the corresponding Active Directory objects may have been created on a different domain controller and may not have been fully replicated to all domain controllers.  In the case where you have removed the Exchange Virtual Server, the Cluster Administrator tool should be used to delete the System Attendant resource and its dependents in order to clean up the cluster configuration.
