If you have a domain controller you can most likely push a registry change or use the netsh command from it to disable privacy addresses with: That toggles a registry setting thus if you can push that you are done. This will still make up the address from RA + EUI-64 component but together that should be stable as MAC addresses rarely change in computers (unless you swap NICs). Another method to get static addresses is to use DHCPv6 of course, but for instance XP does not support that per default.
