Question

我收到以下错误，该用户未与受信任的SQL Server连接相关联。看起来我正在使用我的Windows凭据（这是一个本地帐户）登录。我在域计算机上编写了应用程序并将其移至我的笔记本电脑进行测试。笔记本电脑不在域中，我的web.config列在下面。我可以使用我正在使用的帐户登录SQL服务器并拥有对数据库的完全访问权限。服务器设置为混合身份验证。我正在运行Windows 7，在Visual Studio 2010中使用iis 7.5进行调试。任何人对进展情况有什么想法？

的Web.config

<add name="MediaTrackerConnectionString" connectionString="Data Source=myserver.full.domain.com;Initial Catalog=MediaTracker;" providerName="System.Data.SqlClient"/>

在我的页面中，我有：

           mediaConnection = new SqlConnection("user id=DOMAIN\user;" +
                      "password=XXXXXX;server=myserver.full.domain.com;" +
                      "initial catalog=MediaTracker; " +
                      "connection timeout=30");

我收到错误：

Answer 1

您可以完全访问计算机上运行的SQL Server实例，但您可能需要将您的帐户映射到与应用程序中的数据库接口。

右键单击数据库并转到属性。转到“用户映射”，并为您的用户帐户分配相应的权限。

修改

听起来您可能启用了Windows身份验证模式，在这种情况下，您的应用程序可能正在尝试使用NETWORK SERVICE帐户连接到数据库。从连接字符串中删除凭据，并授予NETWORK SERVICE帐户访问数据库的权限。否则，请确保已启用混合模式身份验证，并使用sa帐户访问数据库。

Answer 2

Here是您想要了解的几点。只是重复文章所说的内容：

如果每次在使用Windows身份验证的应用程序中出现此错误消息，并且客户端和SQL Server实例位于不同的计算机上，则确保用于访问SQL Server的帐户是域帐户。如果正在使用的帐户是客户端计算机上的本地帐户，则会出现此错误消息，因为SQL Server计算机和域控制器无法识别其他计算机上的本地帐户。
如果登录的用户是来自SQL Server域的其他不受信任域的域帐户，则会出现此错误消息。
尝试登录的用户帐户更改密码后，可能会立即显示此错误消息。
如果此错误消息仅在使用Windows身份验证的应用程序中偶尔出现，则可能是因为SQL Server无法联系域控制器以验证用户。
当SQL Server的SPN未被SSPI解释为属于本地计算机时，使用受信任的身份验证对本地连接可以始终显示此错误消息。这可能是由DNS配置错误或具有多个名称的计算机引起的。

用户与SQL连接错误无关
