Two late goals gave Dartford a narrow victory over 10-man Hyde.
Alex Brown fired into the top corner to give the visitors a first-half lead after a strong run from Scott Spencer.
Hyde keeper David Carnell saved substitute Harry Crawford's penalty after Ben Dennis fouled Jacob Erskine in the area.
Adam Griffin was shown a second yellow card for handball, before Crawford levelled with a header and Richard Rose drove in a late winner.
VIEWS FROM THE DRESSING ROOM
Dartford manager Tony Burman told BBC Radio Kent:
"That was agony, for 70 we haven't played well at all.
"No disrespect to Hyde who worked their socks off, but we had too many players putting in a below par performance.
"You can't turn on and off your form like we have done today. Having said that I've got to give the players credit, in the last 20 minutes we've gone on and won the game and all we're concerned about is winning three points."
