Dartford claimed their biggest scalp since promotion to Blue Square Bet Premier when they won 2-0 at Luton Town on Saturday.
Darts, whose victory sent them fifth, were even applauded off by large sections of home fans in the crowd of 6,567.
Tony Burman's side stunned the Hatters by taking a fifth-minute lead when Lee Noble's 40-yard free-kick evaded everybody and caught out goalkeeper Dean Brill.
The second goal, five minutes before the half-time interval, was equally embarrassing for the home defence with centre-half Tom Bonner stealing a march at a Mark Arber free-kick to beat the static Brill.
Boss Burman, pictured, said: "We've had some great results this year, going to Wrexham and getting a 2-2, then winning at Grimsby, but this one has got to be the best so far."
