System.Data.SqlClient.SqlException：用户登录失败

在调试中使用我的项目我没有问题。 但是在IIS中运行它我收到此错误：

System.Data.SqlClient.SqlException：用户’domain \ name-PC $’登录失败。

我可以通过Google找到的首要解决方案是更改不起作用的应用程序池高级身份设置。

我正在使用IIS 7.5，我连接到SQLServer 2012，我的连接字符串在下面。

连接字符串

Answer 1

假设您打算使用Windows身份validation来模拟服务帐户，则必须在IIS和ASP.NET中设置Windows身份validation。

在IIS中，确保添加并启用了Windows身份validation模块。 还要确保您的应用程序池在域帐户下运行，而不是在本地帐户下运行。

在ASP.NET中，确保将身份validation模式属性设置为“Windows”

Answer 2

只需设置Integrated Security=False就可以了，根据True和False之间的注释差异是：

True忽略User ID和Password如果提供）并使用正在运行的进程， SSPI(Security Support Provider Interface ) ，如果提供它将使用它们，这就是MS更喜欢这个的原因。 它们是等效的，因为它们使用相同的安全机制进行身份validation，但就是这样。

Answer 3

如果您的SQL Server尚未配置为使用混合模式身份validation，您也可能会收到此错误 – 它实际上并未告诉您未启用此function！

Answer 4

我有类似的经历，我花了很多时间来解决问题。 虽然，我自己的情况是ASP.Net MVC Core和Core框架。 设置Trusted_Connection=False; 解决了我的问题。

在appsettings.json文件中

 "ConnectionStrings": { "DefaultConnection": "Server=servername; Database=databasename; User Id=userid; Password=password; Trusted_Connection=False; MultipleActiveResultSets=true", }, 

Answer 5

Numpty在这里使用SQL身份validation

而不是Windows（正确）

将登录添加到SQL Server时，如果您使用的是Windows身份validation，也会出现此错误。

Answer 6

我刚刚遇到这个错误，需要几天才能解决。 我们被初始问题中提到的red-herring错误消息抛出一个循环，加上Windows事件查看器错误日志表明类似的东西：

 Login failed for user '(domain\name-PC)$'. Reason: Could not find a login matching the name provided. [CLIENT: ] 

这些都不是真的，用户拥有SQL Server中的所有必要权限。

在我们的示例中，解决方案是将IIS中的应用程序池标识切换到NetworkService 。
