我们的团队离开办公室时，一切都很顺利。 昨晚有一台服务器重启，现在我们的一个encryption站点的应用程序池将无法启动。
我们发现了一个错误和两个警告：
Log Name: System Source: Microsoft-Windows-WAS Date: 5/24/2012 7:29:48 AM Event ID: 5059 Task Category: None Level: Error Keywords: Classic User: N/A Computer: Description: Application pool Kentico6 - WMSEncrypted has been disabled. Windows Process Activation Service (WAS) encountered a failure when it started a worker process to serve the application pool. Log Name: System Source: Microsoft-Windows-WAS Date: 5/24/2012 7:29:48 AM Event ID: 5057 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: Description: Application pool Kentico6 - WMSEncrypted has been disabled. Windows Process Activation Service (WAS) did not create a worker process to serve the application pool because the application pool identity is invalid. Log Name: System Source: Microsoft-Windows-WAS Date: 5/24/2012 7:29:48 AM Event ID: 5021 Task Category: None Level: Warning Keywords: Classic User: N/A Computer: 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. 它看起来像身份有问题，但我们没有改变任何东西，它之前工作正常。 我们检查了日志，没有发现任何可疑的活动。 任何想法是什么导致应用程序池无法启动，或者我能做些什么来缩小问题的范围？
它看起来像我们的应用程序池身份证书有一个错字。 不知道为什么它没有立即影响系统，但重新启动它。
