Barnet have appointed Martin Allen as manager for the second time on a contract until the end of the season.
Allen started his managerial career at Underhill in 2003 and spent 12 months in the job before leaving for Brentford.
He has now returned to the League Two strugglers and will be charged with the task of keeping Barnet in the Football League.
A 1-0 defeat away to Aldershot on Tuesday evening left the Bees three points adrift of Burton Albion, who have several games in hand.
Paul Fairclough has been in caretaker charge of Barnet for the past couple of months since Mark Stimson was dismissed on New Year's Day.
Allen admitted he jumped at the chance to return to Underhill and vowed to pull off a great escape.
"I got the phone call late last night, so I did not have too much time to think and I met Barnet representatives this morning," he told Sky Sports News.
"It's only for five weeks and we'll see how it goes.
"It looks tough on paper, they've won eight games all season, but I was in this situation before with Brentford and we got out of it.
"We've got to play the leaders, Chesterfield, on Saturday, so it doesn't get much harder than that but whatever happens we'll give it a good go.
"When I got the call it was a no-brainer. We are going to have some fun and we are going to stay up!"
Barnet chairman Tony Kleanthous told the club's official website: "It is important that everything possible is done to retain our Football League status and we will support Martin thoroughly in his efforts to turn things round and bring in any new players he feels appropriate.
"We now have to win five or six of our last eight games and everyone is focused on the task ahead."
Allen's first game back in charge of Barnet will be on Saturday when the division's second-bottom side entertain leaders Chesterfield.
The 45-year-old has also been in charge of MK Dons and Leicester City, and has been off the managerial merry-go-round since leaving Cheltenham Town in late 2009.
