We are testing IE 10 in our environment and we are having all kinds of weired issues with SSRS(2008R2) reports being displayed. At this point we were able to identify that setting browser in compatibility mode while navigating through report Manager works fine. But, that's not what we want, because we are dealing with thousands of Users(Non IT). We are trying to add entries to reportserver.config file, so that we can force compatibility mode at Server level, without any success. Is there anyway we can achieve this? I did learnt that for few Web Apps, this can be tweaked from IIS Manager. Looking for a way to make it happen with SSRS 2008R2. Any thoughts are appreciated.
