Accenture is Andersen Consulting. It left and changed its name to Accenture because of internal infighting and politics prior to the Enron scandal that took down Andersen entirely.

The name Accenture was also chosen because they were able to keep using Andersen Consulting's existing ac.com domain w/o interruption.

It wasn't, it was spun out before Enron.
