It appears that the numerically lower IP becomes the “main” IP of the server, even when it’s specified as an “additional” IP. As you can imagine, this becomes a problem very quickly as the firewall rules have been configured for a specific IP, and suddenly it’s different.
Server 2003 did not exhibit this behavior.
After performing the steps as below, I could resolve that issue successfully.
– Install SP2 (May be required)
– Hotfix Install (KB975808)
– Remove all existing VIPs
– Re-add all VIPs using the command – Netsh int ipv4 add address “Interface Name” <ip address> <subness mask> skipassource=true
