如何修复“队列句柄已过时，应该关闭？”

Question

在 Windows Server 2003 上，我们使用以下批处理命令每周一次备份 Windows 消息队列中的消息 (http://technet.microsoft.com/en-us/library/cc773213%28v=ws.10%29.aspx ）：

cd "C:\backup"
echo y | del *.* /Q /s
echo y | mqbkup -b C:\backup

我们有一个 C# ASP.NET 3.5 Web 应用程序运行在与此消息队列交互的同一台计算机上。

备份运行后，当我们尝试从Web应用程序访问消息队列时，Web应用程序。抛出以下错误（如果按预期重建应用程序，该错误就会消失）。 我如何解决它？请帮忙。谢谢。

我必须删除并重新创建队列才能解决过时的句柄错误。之后还必须授予适当的权限。
