copy active directory from 2000 to 2003

[mosaur]

Dear All,
I have a big problem, we are an ISP.
I have 1 Domian Controller and 2 additional all on windows 2000. with active directory about 10000 users.
now I want to move to windows 2003 servers.
I bought 4 serves and install windows 2003 on these servers but how to copy these users(username,passwors.......)from windows 2000 server to windows 2003 I need a solution without any risk.
Thanks,

You don't copy users. You install a 2003 system in the domain and upgrade the domain (not any existing servers) to a 2003 domain. Then you demote the 2000 systems from DC status and you now have a 2003 domain with all your 10,000 users.

Otherwise, you can use the Active Directory Migration Tool (ADMT) but that's considerably more messy in my opinion.

mosaur,

There are probably a dozen threads here about bringing up a 2003 R2 server as a DC in a 2000 server environment. In a nutshell you have to run the adprep commans from the 2nd R2 CD first, on your current schema master, then you can DCPROMO the 2003 R2 servers into your domain. Give them 24 hours to sync up, move all your DNS/DHCP/WINS and any other services that your existing 2000 DC's are running over to your 2003 servers before DCPROMO'ing the 2000 servers out of your domain.

Best of luck.

You know Google is available right??

This thread at the excellent petri.co.il site shows how to update the schema to handle 2003 dcs and then others steps that are necessary. Microsoft also has lots on their technet site.
