Private Sub RetrieveObj()

    ' Declare variables.
    Dim Server As WMSServer
    Dim BCPubPoint As IWMSBroadcastPublishingPoint
    Dim Plugin As IWMSPlugin
    Dim AdminMulticastSink As IWMSAdminMulticastSink

Try
    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Add a new broadcast publishing point.
    BCPubPoint = Server.PublishingPoints.Add("NewPubPoint", _
         WMS_PUBLISHING_POINT_CATEGORY.WMS_PUBLISHING_POINT_BROADCAST, _
