IIS Error: "Unable to use session state server because this version of ASP.NET requires session state server version 2.0 or above." That is the error I receive from IIS when I first hit my website or when the application pool get recycled or IIS gets restarted. This only happens the very first time I hit my website, any other attempts the website pops up like it should. This started happening since the migration to the new servers. I've found some other threads with the same problem but no resolution. http://stackoverflow.com/questions/5678772/unable-to-use-session-state-server-because-this-version-of-asp-net-requires-sessi Any help would be greatly appreciated.
