Reporting services Quartz.net windows服务不执行引用SRS web服务的作业

我使用了ssrs reporting execution service的两个web引用来生成报告。我正在使用quartz.net windows服务安排ssrs报告。当我使用StdSchedulerFactory.GetDefaultScheduler（）时，我的Windows服务正在工作，但当我在Quartz服务中远程执行作业并使用GetScheduler（）时，它不工作

public void Execute(IJobExecutionContext context)

        RS2005.ReportingService2005 rs;
        RE2005.ReportExecutionService rsExec;



        // Create a new proxy to the web service
        rs = new RS2005.ReportingService2005();
        rsExec = new RE2005.ReportExecutionService();

        // Authenticate to the Web service using Windows credentials
        rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
        rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
