What would cause a 500 Internal Server Error when accessing the Report Manager url in SQL Server Reporting Services 2008 R2?

Question

I'm very new to Reporting Services and I'm not even sure what to ask. I was given a server where it was installed. I can run the Reporting Services Configuration Manager and connect. However when I attempt to access the urls (web service and report manager) I get a 500 error. I don't see anything in the event viewer. Are there log files somewhere? I'm suspicious of the IIS setup. In particular, the virtual directories. How should these look? I know this question is broad, but general guidance is appreciated.

Update: After examining the logs, here is the first error:

servicecontroller!WindowsService_0!358!09/07/2010-13:30:52:: e ERROR: Exception caught loading and setting code permissions policy level: System.NotSupportedException: This method explicitly uses CAS policy, which has been obsoleted by the .NET Framework.

After fixing the CAS issue, I now find this error in the log (after my initial attempt to access the web service):

I know that I need to set the NetFx40_LegacySecurityPolicy, however I'm not sure where to set it. I see multiple config files. My best guess was the two web.config files. One was in \ReportServer and the other in \ReportManager. However, that did not seem to have an impact. — Christopher Bennage, Sep 07 '10 at 18:03
Okay, I found the correct config file: \MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer\bin\ReportingServicesService.exe.config This fixed the error in the log, but both urls are still returning a 500 error. — Christopher Bennage, Sep 07 '10 at 18:11

SSRS does not rely on IIS (from SQL 2008 onwards), it uses his own http.sys enviroment to host the web service and the report manager.

Refer to:

C:\Program Files\Microsoft SQL Server\MSRS10_50\Reporting Services\LogFiles

To the possible cause.

With so little detail it is hard to know, If you come up with an error in the logfiles, post it to help further.

In the end, I installed on a server without .NET 4.0 and I was able to get it working.
