Exporting users, groups and their members from a currently installed and importing them to a new active directory (server 2003)

Hi,

I have a problematic active directory currently installed and I need to establish a news dc and reconstruct the current objects in current active directory in it. Since the current AD has lots of problem I absolutely cannot relay on ADMT and use it and its procedures to move objects to new active directory. Is there another alternative to do the job?

Thanks in advance
