Q:

Cannot Start SQL Server Reporting Service

That's the first time I use SSRS so my apologies if I'm asking something stupid. 
I have a SQL Server 2008 R2 already installed with SSRS.  When I try to start the SQL Server Reporting Service I receive this error:

System. ServiceProcess. TimeoutException: Time out has expired and the
  operation has not been completed.     at
  System. ServiceProcess. ServiceController. WaitForStatus(ServiceControllerStatus
  desiredStatus, TimeSpan timeout)    at
  ReportServicesConfigUI.Panels. ServerInformationPanel. StartStopServiceTask(Boolean
  start)

Can someone help me with this issue?  Which tests cna I do in order to debug/fix it?  Thanks in advance! 

A:

If you open sql configuration manager, right click the Reporting Services service, go to properties, then advanced you should see an option to turn on error reporting. 
It will also have the dump directory location.  Check the latest log in there and it should tell you why it couldnt start.
