Running SBS 08 / Exchange 07. The other day we were having some DNS issues. Like an idiot I disabled DNS from binding to any of the IPv6 addresses, and unchecked ipv6 in the ethernet cards properties. Everything was okay until I rebooted the server and it would hang forever. I had to hard power cycle it and found that their is a registry key that can be entered under hkey local machine, system, current control set, services,tcpip6,parameters
After I did that the server would reboot into windows fine. So I re-enabled ipv6 everywhere, and then went in to the registry and removed the key I added. I thought all was well.
Now I relalize that exchange isnt working. When I start its management console is says "Disconnect Mailbox" Also when looking at users in AD all exchange tabs are missing.
When I run the mail troubleshooter I get IPv6 Protocol Not Supported, and a second error, Network Adapter ipv6 Address not supported.
I am scared to disable ipv6 again, but am running out of ideas. Where do I start?
