Today while installing 2008 failover cluster I got error or notification from SQL server that two of my servers have same IPV6 address. Because I don’t use IPV6 and I have disabled it in network properties it was a bit weird to see this message.
Then I run ipconfig command that showed to me lot of Tunnel adapters that were disconnected and created automatically by Vista.
So to have painful installation of new cluster I have disabled IPV6 protocol totally.
Here is solution:
- start run with win key + r or by start menu
- regedit
- go to HKLM\System\CurrentControlSet\Services\Tcpip6\Parameters
- add new dword (32bit) value DisableComponents with value 1
- restart
- enjoy
