SBS 2008 and IPv6

So I just pulled an all-nighter trying to remove an SBS 2003 server from an SBS 2008 domain after a relatively uneventful migration. In fact, the part that I dreaded most – migrating mailboxes – turned out to be the easiest. After cleaning out the AD and transferring everything Exchange to the SBS 2008 “destination” server, I demoted the SBS 2003 server (dcpromo). I then updated the group policy for all the client computers. So I was a little surprised that I spent almost three hours staring at a “applying computer settings” screen when the SBS 2008 server rebooted. Thank goodness I was alone because if servers could cry, the SBS 2008 box would have been very miserable after all the invectives I threw at it. Turns out that I had accidentally disabled IPv6 which was not a big deal when the SBS 2003 server was co-piloting the domain. After restarting the SBS 2008 server for the 100th time (feels like), I initially disabled all exchange services thinking exchange was acting up as usual. That did not work, then I remembered reading somewhere that SBS 2008 acted funny when the IPv6 box was unchecked in the network properties page. So I logged back in (as a different admin user since the original login was having so much trouble) and checked the IPv6 box. It was disabled so I enabled it. When I restarted the server, it came right up. I then restarted the exchange services and life was good again. So if you run into a three-hour long “applying computer settings” nightmare, check to make sure you did not accidentally disable IPv6.

Now, if only I can find out why the users are still getting their folders redirected to the old server even after we configured folder redirection on the SBS 2008 box and removed the login script…
