In-form Dover were denied victory by a late Altrincham equaliser in Vanarama Conference on Saturday.
But Whites still extended their unbeaten run to 10 games after second-half goals from Stefan Payne and a Shaun Densmore own goal.
Dover defender Sean Francis said it was frustrating to come away with only a point rather than three.
He said: "It was so annoying to concede so late in the game. We could have defended better as a team for it though.
"Saying that, we are still unbeaten so that's an exceptional statistic."
With keeper Andy Rafferty suspended following his red card at Lowestoft last weekend, back-up Lee Hook came into the side.
Few chances were created at either end in the first half but Whites broke the deadlock five minutes after the interval when Nicky Deverdics was challenged as he shaped to shoot and the ball deflected off Densmore and looped over keeper Dave Parton.
Altrincham levelled with 16 minutes left when substitute Ryan Crowther produced an unstoppable shot from 25 yards to make it 1-1.
But their joy was short-lived as Chris Kinnear’s men hit back immediately when another deflected goal, this time credited to Stefan Payne put Dover 2-1 ahead.
However, there was still time for another late twist as James Lawrie fired home from 25 yards to snatch a point.
Dover: Hook, Orlu, Francis, Bonner, Essam, Cogan (Wynter 81mins), Bellamy, Deverdics, Murphy, Payne, Stirling. Subs not used: Raggett, Reid, Nanetti, Poole. Attendance: 870.
