Even when Network Load Balancing (NLB) is not currently installed, some NLB registry keys may be present in the registry. Microsoft has identified this as a problem in Windows 2000 Advanced server. The recommended solution also resolves the issue in Windows 2003.

To prevent these error messages from occurring, remove the following registry subkeys (if they exist) after a complete backup of the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\System\WLBS
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS


An alternative method, as recommended by Microsoft, to prevent this event ID from appearing in the system event log, is to modify the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS\Group (if it exists)

Follow these steps:

1. Start Registry Editor. To do so, click Start | Run, type regedt32, and then click OK

Warning: Incorrect use of the Windows Registry Editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

2. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WLBS

3. 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 (Figure 1). To do so, delete the PNP_TDI value in the Value data box, and then click OK.
