I've run into a major pain in the neck a few times lately:
I occasionally run into devices with older web interfaces that are set to RC4, such as older SonicWALLs, but also network switches, copiers, specialized app servers, etc.
All the major browsers have now completely removed RC4 support. Enabling SSL3 in IE no longer works. Same type of error, "sorry, that's not secure, and you're too stupid to know better so we're going to stop you right here." This creates a circular problem. I can't log on to the device because the security is too weak, and I can't fix the setting because I can't GET IN. It's fairly simple to get into the diagnostic page of an older SonicWALL and uncheck the "enable RC4 support" box, but first you have to get there!
I am getting sick and tired of these vendors forcing their "help" down my throat, but I digress.
