Narrative:

Preflight; start; and taxi out were normal. At approximately 100 KTS during takeoff the NWS [nose wheel steering] fail cas illuminated and the aircraft began to drift slightly off centerline. I called the abort and [the pilot flying] stopped on the runway. We reset the NWS and taxied to the ramp without incident.
