Events

Event ID	Source	Message
74	Microsoft-Windows-NLB	NLB cluster [%2]: NLB failed to update the NLB host state in the registry. This will affect the ability of NLB to persist the current state after the system restarts, if NLB has been configured to do so. To predict the state of NLB at the next restart, please delete the HKLM\SYSTEM\CurrentControlSet\Services\WLBS\Parameters\Interface\{GUID}\%3 registry value, which will cause the state at the next system restart to revert to the user-specified preferred initial host state.
75	Microsoft-Windows-NLB	NLB cluster [%2]: The NLB host state was successfully updated in the registry. Current state will persist after the system restarts, if NLB has been configured to do so.
