IPv6 Address Configuration
We are implementing IPv6 in a large network with Windows 7, Server 2008, and Server 2008 R2. Routers are configured to advertise IPv6 prefixes so that SLAAC addresses are generated. We have been using dynamic DNS registration on the forward records in the IPv4 world and would like to continue to do so with IPv6. The problem happens when working with static addresses. Configuring a static IPv6 address results in two IPv6 addresses, one the random SLAAC genertated address, and the other the manually entered static address. Both addresses automatically register in DNS. It seeems that servers should not have addresses changing without notice, and some of them need easy to remember addresses. How can we configure a single static address on the computer? I don't see a way to turn off SLAAC without causing it to simply ignore all router advertisements. Shouldn't there be a way to disable SLAAC without going to those lengths? Preferably something that can be done globally via GPO? Am I missing something?

Just switch of router discovery. This will prevent the client from sending Router Solicitation messages. Thus the client won't get an dynamic/automatic assigned ip addresse. To do so execute the following statement from an elevated command line window: netsh interface ipv6 set interface "Local Area Connection" routerdiscovery=disabled Ralf
