摘要

网站和 Web 应用程序依赖于 Internet Information Services (IIS) 应用程序池的可用性。而 IIS 应用程序池又依赖于 Windows Process Activation Service (WAS)。如果 WAS 没有运行或者在启动或关闭应用程序池过程中发生错误，则网站和 Web 应用程序可能无法响应。

解决方法

停止并重新启动应用程序池

为了恢复为正常操作，有时需要重新启动应用程序池。因为应用程序池依赖于 Windows Process Activation Service (WAS)，所以需要重新启动 WAS。如果重新启动 WAS，可能也必须重新启动 WAS 的 World Wide Web 发布服务 (W3SVC)，这取决于 WAS。

停止和启动应用程序池

停止和启动应用程序池:

停止和启动 WAS

要停止和启动 WAS，请执行以下操作：

启动 W3SVC

要启动 W3SVC，请执行以下操作：
