| Message: | NLB Cluster %2 %1: The adapter to which NLB is bound does not support dynamically changing the MAC address. NLB will not bind to this adapter. %3 %4 |
| Explanation | |
|
To be operated in unicast mode, Network Load Balancing (NLB) must alter the unicast MAC address on the network adapter that it will be using. This event is logged when the network adapter to which NLB is trying to bind does not support dynamic changing of its unicast MAC address. |
|
| User Action | |
|
Replace the network adapter with one that supports changing the unicast MAC address dynamically. Alternatively, operate the cluster in multicast mode. |
