Conference South strugglers Dartford were denied the scalp of League Two Port Vale after John McCombe netted a late equaliser to secure a 1-1 draw in the first round of the FA Cup.
The Darts took the lead when skipper Elliot Bradbrook converted Ryan Hayes' curling free-kick from close range.
McCombe also denied the home side with more than one goalline clearance before nodding home a corner with six minutes remaining.
Chesterfield had few problems seeing off Ryman League Premier Division Harrow to reach the second round. Home goalkeeper Nick Jupp kept his side in it until Scott Boden broke the deadlock and Craig Davies then made it 2-0 in stoppage time.
There were few major suprises elsewhere, although League Two Accrington did beat League One Oldham 3-2.
