My Windows 2012 server would not start yesterday; it was stuck in a continuous restart loop. A quick call to my co-location guys at Alphadex got me into the facility at Manchester's Media City. The Keyboard and Monitor were already set-up, enabling me to get right down to locate the fault.
The fault? A mis-configuration in the registry, fixed by pressing F8 just after POST and then selecting Last Known Good.
After a restart, we were done and back up and running. Excellent service from the Alphadex guys!
