Paddy McCarthy's own goal gifted Derby a point at Crystal Palace and ended their run of five Championship defeats.
Derby keeper Frank Fielding saved a Glenn Murray effort before Chris Martin's 25-yard strike, which took a slight deflection, put Palace ahead.
The Rams enjoyed plenty of possession but failed to break down Palace until McCarthy turned Paul Green's back-post cross into his own net.
And Green was denied a winner in injury time by Julian Speroni's fine save.
The home side, who had not scored in more than eight hours of Championship football, almost ended their drought inside the opening minute.
Darren Ambrose surged forward and his shot was deflected into the path of Murray whose low strike from 10 yards was pushed away by Fielding.
However, Palace's barren run was ended on 499 minutes courtesy of Martin's first goal for the club.
Derby wasted several opportunities to clear their lines and striker Martin, who is on loan from Norwich, fired in a shot from 25 yards which took enough of a deflection to leave Fielding static.
The Rams were allowed large spells of possession throughout the rest of the half but they struggled to break down a Palace defence which had not conceded a home goal in five previous matches at Selhurst Park.
Derby continued to press after the break, forcing five corners in the opening 15 minutes as they enjoyed 80% of the possession but again they did not have the guile to force Eagles keeper Speroni into making a serious save.
However, their endeavour was rewarded when McCarthy turned Paul Green's teasing back-post cross into his own net.
And Derby almost won it in injury time but Speroni was equal to Green's stinging low drive.
