We need to readdress our current network scheme to a totally different IP address, subnet mask and DG.  We are running a 2008 Domain Controller with DHCP and DNS.  Any major loopholes anyone aware of doing this (apart from the obvious like DHCP address output to clients, etc)?  Particularly, will this affect domain operations (FRS, etc.).

For the most part, everything in AD is handled with DNS. It should be noted that you should make sure and create the appropriate subnets in your domain sites and services to match the new setup *before* making the switch. The process for changing IP addresses is to change the address and restart the Netlogon service to update DNS with the new addresses. If that doesn't happen properly, you can run into issues (just so you are aware). There are some applications that don't support IP address changes, so you would want to investigate if that applies to you. You'll also need to go through all of your static DNS records to make sure they match up.
