Brahim, Funny thing, we just completed this very task.
First we pointed all DCs in the Enterprise to the same DNS server (this way everyone worked from a single DNS database for records). We then changed that DNS server's TCP/IP settings to reflect the new IP address scheme. We then ran "net stop netlogon", then "net start netlogon", then "ipconfig /flushdns", then "ipconfig /registerdns" Ensured that new IP showed up properly in DNS. We then moved to the next DC, then the next, then the next. After the IP address change was complete we pointed all DCs back to their original DNS servers.
