I think so, or very similar ones. Sadly the role changes didn't work. The Rick Strahl article hints that my older server is running IIS 7.0 whereas all the other ones are 7.5, and he reckons I MUST use runAllManagedModulesForAllRequest="true" for 7.0. So be it. All of the jumbled clues and arguments eventually lead to this conclusion. It was only a fluke that after a couple of hours I realised that this server was older than the others, and combined with the Static handler error hint that I was led to look at versions (use systeminfo.exe). All of the servers are GoDaddy hosted, and I vaguely recall that the bad one was one of the first provisioned a few years ago. Rick also points out that you can't upgrade from 2008 to R2, or update IIS. I found this when I tried to install SP1 which was offered in the Windows Update list. You get some error xxxxx2e which will lead you down idiotic suggestions to get around it. I also tried to install the specific KB to fix the routing, but it rejects install. *GK*
