Exchange 2007 容易宕機

今天我嘗試登錄我的 OWA (Outlook Web Access) 帳戶，但出現以下錯誤。我試圖啟動遠端桌面連接以重新啟動服務，但我不能（我得到黑屏），我唯一能做的就是物理重置我的伺服器。這種情況每20天發生一次，我不知道為什麼！

結合 RDP 上的黑屏，這表明潛在的 RPC（或更廣泛的網路）問題。檢查您的日誌 - 在伺服器停止工作之前，事件查看器中是否顯示任何內容？

**編輯：**根據您的評論，您將失去與域控制器的連接。（我在這裡假設一個 - 如果您有多個，則您不會與其中任何一個交談。）這解釋了無法獲取郵件以及黑色 RDP 螢幕（它啟動會話，然後嘗試進行身份驗證和掛起。但是，使用本地帳戶登錄到郵件伺服器應該可以。）

了解在這 20 天的周期內域控制器上發生了什麼。也可能是網路問題。如果您沒有看到任何有關服務失敗或記憶體不足的錯誤，那麼它不太可能是郵件伺服器上的問題。這些都是暫時性錯誤，因此如果您解決了根本問題，Exchange 應該會立即反彈。
