Guest Thinkpad21 Posted March 30, 2008 Posted March 30, 2008 Whey trying to verify a Windows 2008 failover cluster for an Exchange 2K7 SP1 CCR ( before adding a second node ), I get the following : Local Area Connection* 9 Adapter Description Teredo Tunneling Pseudo-Interface Physical Address 02-00-54-55-4E-01-00-00 Status Not Operational IP Address fe80::100:7f:fffe%12 Prefix Length 64 Found duplicate IP address fe80::100:7f:fffe%12 on node EXCH-CCR-N1.xyz.com adapter Local Area Connection* 9 and node EXCH-CCR-N2.xyz.com adapter Local Area Connection* 9. I have removed IPv6 check mark from both nodes, but still same thing... I can see that the IP for this adapter is the same, but how would I change this, and I tought that Teredo Tunneling adapter was only for IPv6, and by removing IPv6, it would go away... Just wondering... Thanks !!! --
