从 IIS 服务器运行 SQL 查询时抛出异常？

Question

我使用 Web 窗体构建了一个简单的 ASP.NET Web 应用程序。在默认页面上，单击按钮来运行 SQL 查询，其输出被添加到三个列表框中。源码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;

namespace WebApplication3
{
public partial class _Default : Page
{

    protected void Button1_Click(object sender, EventArgs e)
    {


        SqlConnection myConnection = new SqlConnection("user id=WebApp;" +
                                    "password=[REMOVED];" + 
                                    "server=JC-SRV;" +
                                    "Trusted_Connection=yes;" +
                                    "database=Database; " +
                                    "connection timeout=30");

        string Command = ("SELECT *" + "FROM Table");


        try
        {
            TextBox4.Text = ("Attempting to connect to database...");
            myConnection.Open();
            TextBox4.Text = ("Success!");
            SqlCommand myCommand = new SqlCommand(Command, myConnection);
            try
            {
                SqlDataReader myReader = null;
                myReader = myCommand.ExecuteReader();
                while (myReader.Read())
                {
                    ListBox1.Items.Add("Field 1 " + myReader["Test1"].ToString());
                    ListBox2.Items.Add("Field 2 " + myReader["Test2"].ToString());
                    ListBox3.Items.Add("Field 3 " + myReader["Test3"].ToString());

                }
            }

            catch (Exception ex)
            {
                TextBox4.Text = (ex.ToString());

            }

            finally
            {
                myConnection.Close();
            }


        }
        catch (Exception ex)
        {
            TextBox4.Text = (ex.ToString());

        }
    }
    }
}

当我在 Visual Studio 2013 和 IIS Express 中从我的开发机器上运行时，这可以正常工作，但是，当我将项目发布到安装了 IIS 7.0 的 Server 2008 R2 机器时，会引发以下异常：

System.Data.SqlClient.SqlException (0x80131904): 用户登录失败 '查曼\JC-SRV$'。在 System.Data.SqlClient.SqlInternalConnection.OnError（SqlException 异常，布尔 breakConnection，Action1 wrapCloseInAction) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj, Boolean callerHasConnectionLock, Boolean asyncClose) at System.Data.SqlClient.TdsParser.TryRun(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj, Boolean& dataReady) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlInternalConnectionTds.CompleteLogin(Boolean enlistOK) at System.Data.SqlClient.SqlInternalConnectionTds.AttemptOneLogin(ServerInfo serverInfo, String newPassword, SecureString newSecurePassword, Boolean ignoreSniOpenTimeout, TimeoutTimer timeout, Boolean withFailover) at System.Data.SqlClient.SqlInternalConnectionTds.LoginNoFailover(ServerInfo serverInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString connectionOptions, SqlCredential credential, TimeoutTimer timeout) at System.Data.SqlClient.SqlInternalConnectionTds.OpenLoginEnlist(TimeoutTimer timeout, SqlConnectionString connectionOptions, SqlCredential credential, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance) at System.Data.SqlClient.SqlInternalConnectionTds..ctor(DbConnectionPoolIdentity identity, SqlConnectionString connectionOptions, SqlCredential credential, Object providerInfo, String newPassword, SecureString newSecurePassword, Boolean redirectedUserInstance, SqlConnectionString userConnectionOptions) at System.Data.SqlClient.SqlConnectionFactory.CreateConnection(DbConnectionOptions options, DbConnectionPoolKey poolKey, Object poolGroupProviderInfo, DbConnectionPool pool, DbConnection owningConnection, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionFactory.CreatePooledConnection(DbConnectionPool pool, DbConnectionOptions options, DbConnectionPoolKey poolKey, DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionPool.CreateObject(DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionPool.UserCreateRequest(DbConnectionOptions userOptions) at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, UInt32 waitForMultipleObjectsTimeout, Boolean allowCreate, Boolean onlyOneCheckConnection, DbConnectionOptions userOptions, DbConnectionInternal& connection) at System.Data.ProviderBase.DbConnectionPool.TryGetConnection(DbConnection owningObject, TaskCompletionSource1 重试，DbConnectionOptions userOptions，DbConnectionInternal& 连接）在 System.Data.ProviderBase.DbConnectionFactory.TryGetConnection（DbConnection owningConnection，TaskCompletionSource1 retry, DbConnectionOptions userOptions, DbConnectionInternal& connection) at System.Data.ProviderBase.DbConnectionClosed.TryOpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory, TaskCompletionSource1 重试，DbConnectionOptions userOptions）在 System.Data.SqlClient.SqlConnection.TryOpen（TaskCompletionSource`1 重试）在 System.Data.SqlClient.SqlConnection.Open() 在 WebApplication3._Default.Button1_Click（对象发送者，EventArgs e)ClientConnectionId:0516c418-145d-4558-b9d7-ed2e55c74724

可能值得注意的是，服务器是一个名为 CHARMAN 的域的 DC，而 JC-SRV 是机器名。 SQL 2014 服务器也在这台机器上运行。

任何帮助将不胜感激。

Answer 1

感谢This Post我加了

Integrated Security=False

到连接字符串，它工作得很好

Answer 2

联系您的 DBA 并获取相关 SQL Server 实例上“CHARMAN\JC-SRV$”所需的权限。

注意：我没有添加 cmets 的权限，因此发布我的评论作为答案。
