asp.net - 访问报表服务器时出现 AppPool 权限问题

Question

我有一个在 Windows 7 计算机上运行的 SQL Server 2008 R2 报表服务器以及一个 ASP.NET 应用程序。 ASP.NET 应用程序向报表服务器发出请求以显示报表列表、呈现报表等。我的 ASP.NET 应用程序成功获取报表列表，但当它尝试呈现报表时，出现以下错误:

The permissions granted to user 'IIS APPPOOL\DefaultAppPool' are insufficient for performing this operation. (rsAccessDenied)

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: Microsoft.Reporting.WebForms.ReportServerException: The permissions granted to user 'IIS APPPOOL\DefaultAppPool' are insufficient for performing this operation. (rsAccessDenied)

Source Error: 

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace: 

[ReportServerException: The permissions granted to user 'IIS APPPOOL\DefaultAppPool' are insufficient for performing this operation. (rsAccessDenied)]
Microsoft.Reporting.WebForms.ServerReportSoapProxy.OnSoapException(SoapException e) +89

Microsoft.Reporting.WebForms.ServerReport.EnsureExecutionSession() +79

注意:相同的代码库在运行 Windows 7 和 Windows Server 2008 的多台计算机上运行良好。我已经根据网络搜索尝试了许多不同的方法，但尚未找到解决方案。任何对此的见解将不胜感激。

Answer 1

终于明白了。我的 Reporting Services 配置为本地帐户，而我的 IIS 应用程序池配置为 ApplicationPoolIdentity。我将应用程序池更改为 LocalSystem 并修复了它。希望这些信息对其他人有用，因为我浪费了几个小时来弄清楚这一点。
