昨天我们的团队离开办公室时，一切都运行正常。昨晚服务器重启，现在我们的一个加密网站的应用程序池无法启动。
我们发现一个错误和两个警告：

Description:
The identity of application pool Kentico6 - WMSEncrypted is invalid. The user name or password that is specified for the identity may be incorrect, or the user may not have batch logon rights. If the identity is not corrected, the application pool will be disabled when the application pool receives its first request. If batch logon rights are causing the problem, the identity in the IIS configuration store must be changed after rights have been granted before Windows Process Activation Service (WAS) can retry the logon. If the identity remains invalid after the first request for the application pool is processed, the application pool will be disabled. The data field contains the error number.
看起来 Identity 有问题，但我们没有做任何更改，之前它运行良好。我们检查了日志，没有任何可疑活动。有什么想法导致应用程序池无法启动，或者我可以做些什么来缩小问题范围？
答案1
看来我们的应用程序池身份凭证有拼写错误。不知道为什么它没有立即影响系统，但在重启后却影响了系统。
