ASP.NET Web服務無法與IIS7中的數據庫連接

Question

當我嘗試在IIS7上發布asp.net Web服務應用程序時，在使用Visual Studio進行調試時，我的應用程序可以完美運行。 但是，當我嘗試通過在瀏覽器上鍵入以下內容來從IIS訪問IIS的Web服務時： http://localhost:port/Service1.asmx並單擊該方法，然后單擊“調用”，這會給我這個錯誤：

System.Data.SqlClient.SqlException: The SELECT permission was denied on the object 'Marimi', database 'eMagazin', schema 'dbo'.
   at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 wrapCloseInAction)
   at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, Boolean breakConnection, Action`1 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.SqlDataReader.TryConsumeMetaData()
   at System.Data.SqlClient.SqlDataReader.get_MetaData()
   at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString)
   at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async, Int32 timeout, Task& task, Boolean asyncWrite)
   at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, TaskCompletionSource`1 completion, Int32 timeout, Task& task, Boolean asyncWrite)
   at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method)
   at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method)
   at System.Data.SqlClient.SqlCommand.ExecuteReader()
   at WebService.Service1.GetMarime() in C:\Users\Eduard\Desktop\MaG_beta01\MaG\WebService\Service1.asmx.cs:line 741

我在web.Config中與數據庫的連接是：

<connectionStrings>
    <add name="connection" connectionString="Data Source=EDUARD-PC\EDD;Initial Catalog=eMag; Integrated Security=True;" providerName="System.Data.SqlClient"/>
  </connectionStrings>

我將ASP.NET v4.0 Classic用作應用程序池

我已經在Google上搜索了解決方案，但沒有發現任何幫助。...預先謝謝大家...

“應用程序池標識”對您的數據庫沒有權限：要么不使用集成安全性，要么為擁有數據庫權限的appool創建專用用戶。
