NLB cluster [%2]: The maximum number of actively serviced Extended Affinity connections that could be tracked by NLB is reached. Although NLB will still accept new connections, it will not track the connection state until other connections are closed. This might result in breaking the affinity maintained by the driver during the connection. To resolve this issue, add more hosts to the cluster and/or increase the %3 value under the HKLM\SYSTEM\CurrentControlSet\Services\WLBS\Parameters\Interface\{GUID} key in the registry.
