Hello, I have time-out for reports that last more than 120 sec. I have tried all the steps explained here: http://blogs.msdn.com/b/mariae/archive/2009/09/24/troubleshooting-timeout-errors-in-reporting-services.aspx But i still have time-out. What is strange is that when i go physically on the report machine and use localhost in the address bar, it works just fine. It's a windows server 2003 x64. Thanks for your help.
Sound like network latency problem, you may try obtaining a report on PORT on that server where RS is located. It could be IIS problem too, so see if the default timeout has been set properly
