Windows 2000 server failed

My Windows 2000 server was dying so I replaced it and now have issues rejoining the domain on the windows 2000 workstations. The pc connect to the domain but will not run the login script. I have disconnected one pc from the domain and reconnected and then the login script works. But by doing this I loose all the setting and have to resetup e-mail printers documents etc. Is there a trick to rejoining the domain and not loosing everything.
