我偶尔和随机失败的SQL Server备份与错误消息Operating system error 1394
有谁知道为什么会发生这个错误，我怎么能防止它？
一个小Google使用告诉我： 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.
这是伟大的…但不告诉我为什么会发生这种情况。
SQL服务器备份到Windows 2008 Server上的远程Windowsnetworking共享。 我们运行Active Directory。 有一个由50多个不同版本的SQL Server（2000,2005,2008,2008 R2）组成的整个队伍，运行在Windows 2003,2008和2008R2上（注意自我：我真的需要标准化！）
再次运行备份不会重现该错误。
