IP Address Change on Network

I am Changing the IP Addresses on our network this weekend to a Private IP Scheme.  We are going from 1.x.x.x to 10.x.x.x.  We are on a Server 2003 Domain and AD.  We only have one location and one domain.  I was planning on starting with the Domain Controllers by changing the IP's and then doing a 'ipconfig /flushdns' and 'ipconfig /registerdns'.  Then maybe going to the file-server; exchange server; print server; etc, then also doing a 'ipconfig /flushdns' and 'ipconfig /registerdns'.  I have to change the IP on the printers as well.  All desktops and laptops will get their IP's from DHCP from the routers DHCP server, which will be updated as well.  We have about 8 servers and 35 desktops/laptops. Does anyone have any advice on how to minimize any problems or suggest a better order of operations?  I am starting Saturday afternoon and hope to be finished in half a day.  Nobody will be back in the building until Monday morning.

To keep from going to each desktop and forcing it to get a new address, you might want to reduce your DHCP lease duration to a day or less now, well before changing everything.  You would need to start with your Router/firewall and Main Domain controller.  You should restart your domain controller after you have changed the address and setup a new DNS and DHCP zone for the new Subnet to ensure it is happy.  Then go ahead and change all of the other static addresses.  You will also need to create new ports on your print server to point to the new printer addresses.

Forgot to mention that I am putting in a new Firewall/Router that I have already configured with the new DHCP Server containing the new IP Scheme and DNS as well.  On my domain Controller would I have to create a new Reverse Lookup Zone or would it be created automatically once I ran the Ipconfig /registerdns from the domain controllers?

You will need to create the new reverse lookup zone.
