连接到 SQL 服务器时连接字符串抛出错误

Question

我正在尝试将旧的 Web 应用程序从独立 Windows 2008 服务器移动到 2012 R2 服务器，该服务器处于生产环境中，用于其他一些 Web 应用程序。

我将 SQL Server 数据库移动到专用的 SQL Server 2012，并设置域用户来连接和管理应用程序。我一直收到以下错误，但我不确定为什么用户无法连接。

这些是敏感信息已更改的连接字符串：

<add name="CslaExConnection" 
     connectionString="Database=Databasev3;Server=Server\Instance,50000;User=Domain\User;Password=P@ZZWORD;Enlist=false;" 
     providerName="System.Data.SqlClient" />
<add name="ConnectionString" 
     connectionString="Data Source=Server\Instance,50000;Initial Catalog=Databasev3;Persist Security Info=True;User ID=Domain\User;Password=P@ZZWORD" 
     providerName="System.Data.SqlClient" />
<add name="ConnectionString1" 
     connectionString="Data Source=Server\Instance,50000;Initial Catalog=Databasev3;Persist Security Info=True;User ID=Domain\User;Password=P@ZZWORD" 
     providerName="System.Data.SqlClient" />
<add name="Tools" 
     connectionString="Data Source=Server\Instance,50000;Initial Catalog=Databasev3;Persist Security Info=True;User ID=Domain\User;Password=P@ZZWORD" 
     providerName="System.Data.SqlClient"/>
<add name="MySQLConnection" 
     connectionString="Server=127.0.0.1;Database=MySQLDB;Uid=root;Pwd=P@ZZWORD;Port=3306;Allow Zero Datetime=True;" 
     providerName="MySql.Data.MySqlClient"/>
<add name="CslaExConnectionSynergyContact" 
     connectionString="Database=goldmine;Server=Server\Instance,50000;User=Domain\User;Password=P@ZZWORD;Enlist=false;" 
     providerName="System.Data.SqlClient" />
<add name="ConnectionString2" 
     connectionString="Data Source=Server\Instance,50000;Initial Catalog=Databasev3;Persist Security Info=True;User ID=Domain\User;Password=P@ZZWORD" 
     providerName="System.Data.SqlClient"/>

这是我登录应用程序时收到的错误：

Answer 1

您可以检查服务器连接，您可以在桌面上创建一个空文件并将其保存为 .udl 扩展名。现在打开它，您可以创建连接并进行测试。

完成后，如果用记事本打开.udl 文件，您可以看到字符串连接。如果您使用的是域帐户，请记住使用 "integrated security = SSPI"。

这里有一个使用 .udl 文件创建和测试连接的教程：link .udl

希望对您有所帮助！

凯扎克,

您不能在连接字符串中指定域用户帐户和密码，因为它会将其视为 SQL 服务器身份验证登录。因此，如果您使用域用户帐户运行应用程序，您的连接字符串将采用以下格式：

Data Source=myServerAddress;Initial Catalog=DataBase;Integrated Security=SSPI;
