I have 2 2008 R2 servers built in a cluster. There are 4 network cards 3 are internal and 1 is public. The public network card has the gateway and the rest is done via static routes. When the cluster was built it was built on the private IP of 169 and no other network card was configured. This private IP connects the servers to one another and the databases to one another, in addition the database is stored on a san unit which also has a 169 ip. Those all talk no problem. I can failover the cluster without issues everything is working. My issue is this I have 2 other cards. 10.75.x.x are the ip's and the subnet is the same for both of these cards. One of the 10.75 cards has internal DNS on it. They are both on the domain and if you look in the Network connections you see the domain name associated with both cards. The public IP has this too - it's connected and has the domain name associated with the nic card. The 169 ip is unidentifed. This server pulls images for xrays so you go to your browser type in the clusterd ip address it brings you to a prompt and you type in user name and password and you can read the (Xray) images. The problem unless I put a gateway in the 169 network card you can't read the image. It will not load. The 169 ip's are really only for management and should not and will not be routed to everyone. I've check the routing (static routes) they are all correct. I can't figure out what this issue could even be. Except to rebuild the cluster with all the nic cards as they are and maybe by some miracle this will start working. I have a 2003 clustered server built the same way same type of configuration and it's working fine. Has anyone experianced this?
