另一个解决方案是确保您的报告服务正在运行。尝试重新启动服务。
Another solution, make sure your Reporting service is working. Try restarting the service.
扫描 C:\Program Files\Microsoft SQL Server\MSSQL.1\Reporting Services\LogFiles 中的日志文件并找到以下异常： Microsoft.SqlServer.ReportingServices2008.RSConnection+MissingEndpointException：尝试连接到报表服务器失败。检查您的连接信息以及报表服务器是否是兼容版本。 ---> System.Net.WebException：请求失败，HTTP 状态为 404：。
您可能已将 /reportserver/ 应用程序配置为无法通过 http://localhost/ 访问...尝试遵循以下操作：
1) 将 localhost 主机头添加到托管 /reportserver/ 的网站，并确保可以通过该路径访问该应用程序
2) 编辑文件 C:\Program Files\Microsoft SQL Server\MSSQL。 1\报告Services\ReportManager\RSWebApplication.config 并将 ReportServer 的完整 url 添加到 ReportServerUrl 标记中（无结尾/必要），并从 ReportServerVirtualDirectory 中删除该值（否则您会遇到令人讨厌的、不精确的异常）。然后您必须回收报告管理器使用的应用程序池，以便重新加载配置文件。
Scan the logfiles in C:\Program Files\Microsoft SQL Server\MSSQL.1\Reporting Services\LogFiles and find the following exception: Microsoft.SqlServer.ReportingServices2008.RSConnection+MissingEndpointException: The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version. ---> System.Net.WebException: The request failed with HTTP status 404:.
It might be possible that you have configured the /reportserver/ app to not be reachable via http://localhost/... Try following the below things:
1) add the localhost hostheader to the web-site which hosts the /reportserver/ and make sure the app is then reachable via that path
2) edit the file C:\Program Files\Microsoft SQL Server\MSSQL.1\Reporting Services\ReportManager\RSWebApplication.config and add the full url to the ReportServer into the ReportServerUrl tag (no ending / nessesary) AND remove the value from ReportServerVirtualDirectory (otherwise you get nasty, unprecise exceptions). THEN you must recycle the app-pool used by the Report-Manager so that config file is being reload.
我知道这篇文章是很久以前的事了，但我在这里发布了答案，以防其他人面临同样的问题。
我为解决此问题所做的是将 URL 从报表管理器 URL 更改为 Web 服务 URL。
