Problems building a Windows 2008 Failover cluster

[Guest Thinkpad21]

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 !!!
