Alan Lee wrote himself into club folklore as he scored a last-minute winner against Brentford to seal back-to-back promotions for Ronnie Moore's side against all the odds.
Here's what the 14 players who played that day are doing 15 years later.
Paul Pettinger
The goalkeeper was in and out of the side during the promotion campaign, but was in possession of the gloves for the Brentford clash and made a vital save off Lloyd Owusu. He was released at the end of the 2000-01 season and headed into non-league. He had his own building firm and now works in plant hire.
Marvin Bryan
Bryan was a versatile option for Rotherham and was deployed in the right wing-back role in this clash. He stuck around for the Millers' first two seasons in the second tier but left the game after his release in 2003. He worked as a driving instructor but recently worked in private security in the Middle East.
Rob Scott
The striker-turned-defender played a key role in the Millers' promotion and subsequent stay in Division One before leaving post-relegation in 2005. He went into management after retiring, forming a fruitful partnership with Paul Hurst. The two parted ways a couple of years ago and Scott, whose brother Andy managed the Millers, works as a radio summariser and also has business interests.
David Artell
Rotherham-born Artell was living the dream as a figurehead of his boyhood club's promotion season in his debut year. The central defender had a solid lower league career and amazingly is a current international following Gibraltar's emergence in the last 18 months. He works for Crewe's academy and also has studied for a degree.
Guy Branston
A bona fide cult hero, Branston is a key figure in the club's history owing to his antics over his five-year stay. He left the club in 2004 and enjoyed a journeyman status throughout the rest of his career. Now retired, the centre-half is Notts County's chief scout and also has two online businesses.
Paul Hurst
Hurst is Mr Rotherham United
as no one has made more appearances in a red and white shirt than the
left-back. He is currently the Grimsby manager, trying to win promotion to the
Football League.
Kevin Watson
Watson has the honour of captaining a double-promotion-winning side and he was majestic throughout the campaign. But things turned sour for the midfielder, who was hounded out by boo boys the following season. Post-retirement he has worked as a pundit for Sky Sports and was recently sacked as Stevenage's assistant manager.
Paul Warne
The striker is a fans' favourite owing to his long service to the Millers. A key figure in both promotions, he stuck around in the second-tier days too before returning to see out his playing days at Don Valley. He is currently the fitness coach having worked under the last four management teams.
Stewart Talbot
The hard man of the Millers side, Talbot scored the equalising goal against the Bees before going off injured at half-time. A mainstay of the side following promotion, Talbot worked in childcare after hanging up his boots, but is now employed as a railway engineer.
Alan Lee
Lee's ecstasy-inducing goal which secured the rise won him a place in the hearts of all Rotherham fans and he was the star asset in the next two seasons, eventually being sold for close to £1million. A strong career followed before a knee injury forced retirement. He currently works for Ipswich's academy.
Mark Robins
It was Robins' goals that put Rotherham in with a chance of promotion after a fine campaign. He followed that up in Division One and stayed at the club, eventually going on to manage them. Success looked on the horizon until Barnsley turned his head in 2010. He recently left Scunthorpe.
Jeff Minton
Minton was a late-season arrival on loan following injury and suspensions and he came on for Talbot at the break. He headed into non-league not long after his Millers exit and played as recently as 2012.
Chris Sedgwick
Coming through the ranks at Millmoor, Sedgwick was a firm favourite with the crowd. Like Lee, he impressed in the second tier and was sold to Preston in 2004. The right winger is currently on the coaching staff at Bury.
Richie Barker
Barker largely provided back-up for Lee during his first spell at Millmoor but made his own entry into the history books at Hillsborough the following season. He returned for a second spell late in his career. Barker has had several jobs as a manager but currently is the MK Dons' assistant manager.
