Kevin Nolan is targeting a quick turnaround after seeing his side beaten 1-0 by Cambridge United.
Medy Elito's goal on the half-hour mark condemned the Magpies to defeat at the Abbey Stadium and the County chief was left frustrated by his team's performance.
"I'm deeply disappointed because I thought we were starting to get back to where we were and I feel we have come away from that today," he said.
"There wasn't much in the game but we didn't deal with Uche Ikpeazu well at all tonight. We looked at their strengths and we didn't deal with any of them and we didn't do anything to exploit their weaknesses.
"I have said to the lads we have another quick turnaround and another big game on Saturday where we have to get three points."
The manager believes his side are currently low on confidence in front of goal after being shut out twice in as many games on the road but does not think it will be too long until they are firing on all cylinders once more.
"I can't put my finger on it but we will be working hard over the next 72 hours to make sure we are ready for Stevenage on Saturday," he said.
"There's a lack of confidence to try something in the final third for a lot of them.
"With the quality we have across the frontline we have to start breaking teams down much more than we are.
"I believe it won't take us long to get back to where we were this time last week after a positive result against Carlisle."
