SYMPTOMS
On a Microsoft Windows Server 2003-based computer, you may receive the following event ID in the system event log during startup:
Event ID: 7000
Event Source: Service Control Manager
Description:
The Network Load Balancing service failed to start due to the following error: The service cannot be started, either because it is disabled or because it has no enabled devices associated with it. Network Load Balancing is not installed on the system.
You receive this event ID even though the Network Load Balancing service is not installed on the computer.
CAUSE
This issue may occur if the Network Load Balancing service is referenced as a component in the startup group of a third-party service.
WORKAROUND
To prevent this event ID from appearing in the system event log, modify the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS\Group registry value (if it exists). To do so, follow these steps.Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
Start Registry Editor. To do so, click Start, click Run, type regedit, and then click OK.
Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS
Back up this registry subkey. To do so, follow these steps:
On the File menu, click Export.
Select a location to save the file to, type a descriptive name for the registry subkey (for example, "WLBS"), and then click Save.
Important note If you want to install Network Load Balancing in the future, remember to do one of the following before you bind Network Load Balancing to any adapter:
Restore the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS registry subkey from the saved backup.
Change the value of the Group registry entry back to PNP_TDI.
In the right pane, right-click the Group registry entry, and then click Modify.
By default, the Group string value is set to PNP_TDI. To prevent the occurrence of event ID 7000, set the value of the Group entry to an empty string. To do so, delete the PNP_TDI value in the Value data box, and then click OK.
Quit Registry Editor.
