SYMPTOMS

Link Local ISATAP addresses are not created for the virtual IP address used by the Network Load Balancing (NLB) feature on a computer that is running Windows Server 2008 R2. This hinders the usage of NLB nodes as a ISATAP router.

CAUSE

This problem occurs because the IP Helper service does not let virtual IP address interfaces generate ISATAP tunneled addresses or 6to4 tunneled addresses as designed.

For the DIP address ( Dedicated IP ) you will have an ISATAP address available but for the VIP ( Virtual IP ) there is no possibility of having Global Addresses support for the NLB VIP address ( Virtual IP) and no ISATAP addresses can be configured for a VIP.

RESOLUTION

After you apply this hotfix, Link Local ISATAP addresses (FE80::5EFE:'IPv4 address') are generated for the virtual IP addresses and therefore the NLB cluster can act as a ISATAP router. A Link Local ISATAP address is sufficient to act as a ISATAP router because the default route on ISATAP hosts always points to the Link Local ISATAP address of the ISATAP router.

There are no global routable ISATAP addresses (200x::5EFE:'IPv4 address') generated for the virtual IP addresses. This is expected.
