Abstract: The Dzero experiment studies proton-antiproton collisions at the Tevatron collider based at Fermilab. Processing, managing and distributing the large amount of real data coming from the detector as well as generating sufficient Monte Carlo data are some of the challenges faced by the Dzero collaboration. SAMGrid combines the SAM data handling system with the necessary job and information management allowing us to use the distributed computing resources in the various worldwilde computing centres. This is one of the first large scale grid applications in High Energy Physics. After succesful Monte Carlo production and a limited data reprocessing in the winter of 2003/04, the next milestone will be the reprocessing of the full current RunII data set. This consists of ~250 TB of data, encompassing one billion events and will start in April 2005.
