ACCRINGTON boss John Coleman admitted it was a real "kick in the teeth" after Barnet scored a last gasp penalty to take the second round tie into a replay at Underhill.
Stanley had battled with ten men for 53 minutes after John Miles was dismissed for a dangerous challenge on Ismail Yakubu and then, in injury time, Dean Winnard was judged to have pushed Jake Hyde in the area.
John O'Flynn took the spot kick to break Stanley's hearts - and they have to make the trip to London on Tuesday December 8 for the right to face Gillingham at home in the third round.
"It wasn't a penalty," fumed Coleman. "Dean had his hand on his shoulders but has not done enough to push the lad over yet he has gone down. He was desperate but he has prospered from it.
"Everything that could go against us has. We did everything to beat them yet it is a replay.
"If you see the sending off again it wasn't a sending off. Even the staunchest Barnet fans will agree. I can't say anything about the referee as I will get into trouble but he rushed to make a decision and it was the wrong one.
"The lads worked their socks off with ten men and the best team didn't win but that's cup football. There will be a lot of hard luck stories in the FA Cup and we are just another and we have to take it on the chin."
Barnet boss Ian Hendon said: "It.was a hard fought game as we knew it would be - it was a fully committed match - and we are just pleased to be in the hat.
"It was a penalty and I am told John tucked it away although I never watch penalties!
"It was a frustrating game for us against ten men as we created chances but we are pleased to take them to our place.
"We have got to take a bit of pride that we kept going until the end and we came from behind twice.
"We have lost our last six away games and gone off track abit so hopefully this gets us back on track."
On a muddy pitch, Stanley had the best of the early chances with Bees keeper Jake Cole stopping Michael Symes' shot from the edge of the area finding the top corner of the net.
And striker Bobby Grant should have opened the scoring when he got on the end of Sean McConville's right wing cross but he glanced his header wide.
And the Reds took a deserved lead against their League Two rivals on 29 minutes when, after a period of pressure around the box, Symes put a good cross in from the right wing and Grant got a touch to flick it in off the far post. It was the frontman's 10th goal of the season.
But the home side were reduced to ten men on 37 minutes when Miles challenged Yakubu and stood on him as he tried to recover and he saw red - the first of his career.
And they lost goalkeeper Ian Dunbavin to injury on 43 minutes, with him replaced by Liverpool loan signing Dean Bouzaniz, who the club only snapped up on Thursday, and was making his league debut.
The Bees tried to step it up with Albert Jarrett having a shot deflected just wide as they looked to capitalise on their one man advantage.
And they got it a minute after the restart when a Jarrett cross from the left was headed down by Yakubu at the far post and it found the back of the net.
But it didn't last long as the ten men came back with a superb solo effort from Symes on 50 minutes. He outpaced the Barnet defence and got on the end of Grant's through ball and finished low into the bottom of the net.
And it could have been three but Symes, with a free header, sent the ball inches wide at the far post.
The Bees looked for the equaliser but Bouzanis pulled off a one-handed save to keep out O'Flynn's effort and sub Albert Adomah could not pounce on the rebound.
The visitors appealed for a penalty on 83 minutes when Andy Procter tackled Adomah in the area but referee Steve Pawson ignored the Barnet pleas.
But he listened to the one in injury time to upset Coleman.
