Darlington's administrators have terminated the contracts of the club's interim manager Craig Liddle and the remaining playing staff.
The move puts Saturday's home game with Fleetwood in doubt, with the Football Conference setting a deadline of Wednesday to decide if it goes ahead.
In a statement, administrator Harvey Madden said there was "no alternative" given the club's financial position.
He also said that, despite interest, no formal takeover bids had been received.
The statement read: "Given the current financial position of the club and, as a consequence of my legal obligations, I have had no alternative but to terminate the contracts of all playing staff and the retained administration staff.
"Notwithstanding this, there remain parties interested in either injecting funds into the club to enable it to continue operating or acquiring the club.
"Every effort is being made to progress this to try to save the club. However, at this stage I have still not received any formal offers and unless a deal is concluded as a matter of urgency, time will have run out for Darlington Football Club."
"To say I feel sick is an understatement," said Marc Bridge-Wilkinson on his Twitter account, while team-mate Paul Arnison told of his frustrations at being made redundant and defender Aaron Brown expressed surprise at being asked to train for the Fleetwood game.
Adam Rundle, who was one of the players to have accepted reduced payments to ensure the club fulfilled the fixture at Barrow earlier this month, was equally disappointed.
"Not a good day if you're a player - even got taxed on the £200 we were offered for the Barrow game, [I am] hoping Darlo survive though, looks promising," Rundle said on his social networking account.
Since that time the club has cut costs by initially reducing the off-field staff, while players who had not been paid handed in their notice and left the club.
, although negotiations now appear to have stalled.
Meanwhile Liddle has revealed he will continue to work with the youth team for free with the funding for the side guaranteed by the Football League until the end of the season.
The 40-year-old has represented the club as both player and coach, and had previously combined running first-team affairs with a head of youth development role.
