“作業系統錯誤 1394” - 如何預防？

Question

我的 SQL Server 備份偶爾會出現隨機故障，並顯示錯誤訊息Operating system error 1394

有誰知道為什麼會發生這個錯誤以及如何防止它？

一點谷歌搜尋告訴我：http://msdn.microsoft.com/en-us/library/windows/desktop/ms681385%28v=vs.85%29.aspx

ERROR_NO_USER_SESSION_KEY
1394 (0x572)
There is no user session key for the specified logon session.

這很棒......但沒有告訴我為什麼會發生這種情況。

SQL Server 備份到 Windows 2008 Server 上的遠端 Windows 網路共用。我們運行活動目錄。有超過 50 個不同版本的 SQL Server（2000、2005、2008、2008R2），運行在 Windows 2003、2008 和 2008R2 上（自我提醒：我真的需要標準化！）

再次運行備份不會重現該錯誤。
