    Failover Cluster Validation Report failed for Duplicate IP address Windows 2008

    Cluster validation wizard is used to check pre-requisite\best practices before building the cluster. While playing with my lab, I came across a issue under Network Test.

    Error:
    Found duplicate IP address fe80::100:7f:fffe%14 on node node1.vodka.com adapter Local Area Connection* X and node node2.vodka.com adapter Local Area Connection* X.

    ipv6probs

     

    Resolution:
    It turns out that this is the result of the Teredo, an IPv6 Tunneling Protocol. Teredo allows IPv6 communications to pass through IPv4 NATs and IPv4 servers. However Teredo gives an identical IPv6 address to its network interfaces, which Failover Clustering flags as an error since it require unique IP addresses.

    So how do you fix this? There are 2 ways, some details are provided here: http://technet2.microsoft.com/WindowsVista/en/library/91d35c9f-3049-44f4-b711-743dc152c7c31033.mspx?mfr=true

    1) Disable Teredo through command line

    a. Open ‘Command Prompt’ and ‘Run as Administrator’
    b. Type:
               i. > netsh
              ii. > interface
              iii. > teredo
              iv. > set state disabled
    c. Teredo will now be disabled

    cmd

    2) Disable Teredo through the registry

    a. Open the Registry Editor

    i. This can be done through an elevated Command Prompt and typing ‘regedit’

    b. Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6

    c. Right-click on the ‘Parameters’ tab, select ‘New’, choose ‘DWORD’

    i. Enter the following name (including capitalization): “DisabledComponents”

    d. Double-click on “DisabledComponents”, select ‘Hexadecimal’, under ‘Value data’

    i. Enter “8”

    e. Click ‘OK’
    f. Restart your machine
    g. Teredo will now be disabled

    reg

    But what about disabling Teredo through Device Manager?  This will only disable the Teredo adapter so the system does not see it anymore, however this does not disable the underlying logic.  This could cause issues later, so it is recommended to disable it through the command line or the registry.

    Run Validate and this test will now pass. Enjoy your fully supported cluster!

    Troubleshoot Active Directory Logon issue – By Anang Kumar

    • Note the error message (Sometime the error message is very specific )
    • Login to the machine using local admin account
    • Check the system Date and time / Time zone – Make sure they are similar to authenticating DC
    • Check DNS – Make Sure they are pointing to Right DNS (DNS which is alive and doing the name resolution)
    • Check DNS records with the help of NSLOOKUP
    • Ping the DC – IP, Netbios Name and FQDn
    • Ping the DC to DC with 1500 MTU
    • Run Netdiag and check DNS and Trust and Kerberos test
    • Make sure NIC card is enabled of “register me in DNS”
    • Check event viewer for any know errors like Userenv, Kerberos, netlogon
    • Enable netlogon log and do the further troubleshooting  

    Don't forget to post your comments :)
