VMware 4.1: Hardware Status tab: An error occurred, please try again in another vSphere session?

最近開起VMware 4.1點選Hardware Status出現 An error occurred, please try again in another vSphere session?

1.啟動vSphere Client，連接到 vCenter Server 選 Administration > vCenter Server Settings > Advanced Settings。
2.選 VirtualCenter.VimApilurl 和 VirtualCenter.VimWebServicesUrl 欄位，將URL改為IP。
3.進入VMserver 主機，將VMware VirtualCenter Server及VMware VirtualCenter Management Webservices 服務重新開機。

目前進入就出現圖表了
