Troubleshooting Report Manager Problems

Use this topic to troubleshoot problems that you encounter when using Report Manager.

A network error occurs when launching Report Manager as http://localhost/reports

If you get a network error when starting Report Manager, you might need to adjust the LAN settings for your browser. In Internet Explorer, open the Internet Options dialog box, click Connections, click LAN Settings, and select Bypass proxy server for local addresses.


You can also specify Web.config settings to configure proxy server settings. For more information, see Planning for Extranet or Internet Deployment.

Report Manager cannot be started

If you can access the report server at http://<webservername>/reportserver but you cannot start Report Manager, check the report server virtual directory setting in the RSReportServer.config file and verify that it is referencing a valid report server instance. For more information, see RSReportServer Configuration File.

Report Manager starts slowly

Report Manager requires extra time to load the initial page. Additional wait time is required to start ASP.NET. After the initial page opens in the Web browser, subsequent application pages open much faster.

Selected Pages in Report Manager do not open

If you are using Internet Information Services (IIS) 6.0 configured with default settings on your report server, you must add the Web server name as a Trusted Site (for example, http://mywebservername). Otherwise, you cannot open the New Folder page, New Data Source page, and Upload File page from the Contents tab. Also, the frameset used in Report Manager Help does not open correctly.

Report Manager or the report server runs very slowly

In some circumstances, ASP.NET applications run very slowly on computers that are running anti-virus software. If the Report Server Web service is restarting frequently, and you are running anti-virus software, you can obtain an ASP.NET fix from Microsoft Customer Support Services.

Symptoms include Web applications or Application Domains restarting for no apparent reason, slow performance, session restarts, and more. For more information about the symptoms, cause, and resolution, see Microsoft Knowledge Base article 821438.

You can find out whether there are excessive server restarts by viewing the number of reportserver_<timestamp>.log files. A new log is created each time the server starts. A large collection of logs created at very short intervals is an indication that the conditions described in article 821438 exist on your server.

Report Manager is empty

If you are running Report Manager on the same computer where the report server is configured, you may experience permission issues that result in report manager displaying an empty page with no items or folders visible.

Report Manager fails after you enable FIPS compliant algorithms in Local Security Policy

After you enable the Local Security Policy "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing", you are not able to use Report Manager. When you open Report Manager, your browser will be empty or show an "HTTP 500 Internal Server Error". A SQL Server 2008 R2 or later version of the report server will add an error message similar to the following in the report server service log file:

ui!ReportManager_0-1!1708!02/27/2010-08:02:03:: e ERROR: System.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.

To work around this issue: At this time, there is no known work around. Report Manager does not support the Local Security Policy "System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing". If you want to use Report Manager you need to disable the setting and restart the report server service.

This issue applies to: SQL Server 2008 Reporting Services and SQL Server 2008 R2 Reporting Services.
