Windows 2003 - demote, rebuild, promote

hi
I am looking at rebuilding one of my windows 2000 domain controllers.  It originally held all the FSMO roles but these were moved to a new DC 3 days ago.  There are no errors on the DC's relating to replication or AD etc.

My plan is to demote server1, rebuild it with Windows 2003, and join it back into the domain with the same name and IP address.  It all sounds straight forward but i need to know if there are any gotcha's in doing it this way??

thanks

If your domain consist of all the 2000 domain controller then you need to extend the schema of the 2000 domain

other wise you cannnot join 2003 DC to 2000 domain

run adperp /forestperp

adpere / domainprep

good practice is to clear all the DNS records and manually remove the old DC entries from sites and services, and also ADUC aas dcpromo doesnt always cut it

thanks.  Sorry i wasn't clear but I already have a win2k3 DC and the schema has been extended atc.

all i need to do is demote, rebuild, and promote the newly built one.  

Jay_Jay70 - thanks, I found I had to do this when i recently removed another DC that was about die!  From memory i needed to remove the DC from DNS but not AD sites and Services
