Re: Did they try turning it off and on again?
Reply to: You usually test turning off one IT system. It's very rare that you test turning off your entire IT estate and then bring it all back online. You usually discover circular dependencies. The classic being you can't login to your SAN/VM farm as authentication is via your local AD - which is hosted on said platform which is offline because you can't login to turn it back on again.
You hit the nail on the head there!!
I've had to help out in that exact situation, but luckily it was little easier to resolve, as it was only a DNS issue.
