Where are all the places Sql Reporting Server Logs Errors?
As far as I know SSRS logs to the Event Log, the filesystem and its own database.
The database is typically the most easily available one. You just login to the ReportServer database and execute
select * from executionlogThis only logs the executions though. If you want more information you can go to the Trace Log files, which are usually available at (location may of course vary):
C:\Program Files\Microsoft SQL Server\MSSQL.3\Reporting Services\LogFilesThese are quite verbose and not really fun to look through. But they do log a lot of stuff.
If you're searching for an error you can go to the Windows Application Log (Under Administrative Tools in your control panel)
