Cannot Ping Nlb Cluster Ip From Different Subnet
To identify NLB-enabled hosts when using switch or network tracing software look for MAC addresses that start with 02. Important: The virtual IP address must belong to the network. By default, a LAN switch floods multicast traffic within the broadcast domain, consuming bandwidth if several multicast servers send streams to the same segment. If you want to stop cluster operations on all cluster hosts, right-click the cluster, point to Control Hosts, and then click Stop. http://thumbd.net/windows-server/cannot-ping-windows-2008-server-firewall-disabled.html
When invoking the Network Load Balancing remote control commands from a computer outside the cluster, there is no response from one or more cluster hosts. Select the required network, and then click Configure NLB Setting. Entries RSS Comments RSS

North by North by North by South East Who are the people on this picture? Communication between cluster hosts is not affected, because each cluster host retains a unique MAC address. I do this from a separate machine, always using the ip address.
Logged to MS and configured NLB to use multicast, but now we are still not able to ping to the NLB VIP from other VLAN's. Cause: If your cluster is configured for unicast mode, a switch might have learned the NLB network adapter's MAC address. But no where do you describe how to set this up. Nlb Host Status Converging If NLB is running in Unicast Mode, everything works fine.

To check if IP is configured correctly: In the Forefront TMG Management console, in the tree, click the Networking node. Clear the ARP cache on the NLB node and try to ping the NLB; the ping will fail.
The cluster is made up of member hosts, and each host is bound to a public IP address (or addresses) which resolve to the cluster itself. Nlb Cluster Ip Not Reachable Repeat this for each member. If not, click Enable Network Load Balancing Integration to configure NLB. In the Cluster operation mode area, check if Unicast is selected.

Host 1 is priority 1, host 2 is priority 2.

Another option to avoid flooding non-cluster computers is to place a network hub between the switch and the NLB interfaces, and then disable the MaskSourceMAC feature. You’ll be auto redirected in 1 second. Solution: If you plan to use a 64-bit version computer environment, you must use the 64-bit NLB version.

Solution: Carefully review (and if necessary, correct) each of the settings on the second host—for example, the cluster IP address, dedicated IP address, and port rules.
The cluster is configured to use unicast because I need communication between hosts using the dedicated NICs and I don't have a suitable router for multicast. This documentation is archived and is not being maintained. If you do not want to use multicast support, you can interconnect the cluster hosts with a hub or coaxial cable instead of with a switch. Windows 2012 Nlb Converging Alternatively, you can install NLB by typing the following command: Copy servermanagercmd.exe -install nlb After NLB is installed, you can configure an NLB cluster by using Network Load Balancing (NLB) Manager.
Click Install. Cause: You configured the cluster's IP address before NLB was bound to the network adapter. Solution: Assign a dedicated IP address to each host. Configure the switch or configure Forefront TMG for multicast: In the Forefront TMG Management console, in the tree, click the Networking node.
However, specifying the host by its priority (ID) works.
