Loick Pires scored the winner as Woking came from a goal down to defeat 10-man Stockport at Edgeley Park.
Alex Kenyon put County ahead, nodding in a cross from Matty Mainwaring, who returned to Stockport earlier this week after a spell with Hull City.
But Gavin McCallum levelled, drilling the ball home with his left foot.
Pires latched onto Dean Sinclair's pass to give his side the lead, before the hosts had Jon Nolan sent off for two bookable offences late on.

Woking manager Garry Hill told BBC Surrey:
"I think we've been playing very well and one thing we are learning is not to give teams head starts.
"We had a lot of possession and had the better chances. As far as I'm concerned, we deserved the equaliser and felt confident we would win.
"I have every belief in these players. They're all working hard for us and it's a big win for the team."
