Danny Hylton's brace for Aldershot Town avoided an upset against Hendon, and relieved some of the pressure on manager Dean Holdsworth.
The Isthmian Premier Division side took the lead when a 30-yard volley from Dean Cracknell, a plumber by trade, arrowed into the top-left corner.
Hylton equalised after converting winger Kieron Cadogan's cross from the right.
The 23-year-old then sealed the win, tapping in Craig Reid's cutback.

Aldershot manager Dean Holdsworth told BBC Surrey:
"We showed a lot of character. We passed the ball well, had a lot of possession and scored two good goals.
"I didn't want to be in the headlines tomorrow for this football club having a giant-killing. You have to just win the game and get on with it.
"We've won today and we're in the next round. That's the most important thing."
