As I understand it the only way to turn off captcha is for us to change our password, this will then disable captcha automatically.
What I'm unsure of is what will happen to the client machines if I change our password and then change it back straight away. I also can't find any documentation as to whether there's a password policy in place that will prevent this (remember last x passwords)
I need absolute certainty and a full understanding as I don't want to lose remote connectivity to hundreds of machines if it goes wrong.
