Huddersfield stunned Cambridge with a pair of stoppage-time goals to beat the Blue Square Premier team 2-1 in a dramatic climax to their FA Cup first-round replay.
Lee Clark's npower League One outfit looked like slumping to a dismal 1-0 defeat at home, with Rory McAuley's 53rd-minute goal almost enough to cause an upset.
However, Lee Peltier levelled up for the Terriers in the first additional minute and Gary Roberts fired in the winner three minutes later.
In-form Charlton will face Corby Town or Luton in the second round after Kyel Reid's close-range strike in the 18th minute was enough to beat Barnet at The Valley.
Dartford's failure to finish off Port Vale in the first game between the teams, when they conceded a late equaliser, cost them dearly as the Conference South side were thrashed 4-0 at Vale Park.
Marc Richards scored twice, the first a penalty, and there were also goals for Sean Rigg and Justin Richards for Vale, who will meet Accrington in the second round.
Fleetwood were beaten at the second attempt by Walsall, who had goalkeeper Jimmy Walker to thank for a draw in the first match between the teams.
Walsall were improved and won 2-0 with both goals from Reuben Reid. A trip to Torquay awaits them in the next round.
Leyton Orient were pushed hard by Dagenham and Redbridge in a keenly contested derby at Brisbane Road, but eventually prevailed 3-2.
Scott McGleish and Alex Revell put the home side 2-0 up early on, but two goals inside a minute midway through the second half - a penalty from Danny Green and long-range strike from Solomon Taiwo - hauled Dagenham level. However, McGleish fired in his second goal of the evening for Orient in the 76th minute and they can look forward to a televised second-round clash with Droylsden on November 29.
