Component key missing from Configuration Registry
A component key necessary to your configuration is missing in the Registry. Therefore, the current operation cannot be completed. This message is most likely to appear after a new network component has been installed.
Restart the computer, then choose Network from Control Panel and choose Binding to redo the binding. If the problem continues, ask the administrator to do the following: Edit the Registry, removing the variable \Software\Microsoft\Ncpa\CurrentVersion\Bindfile. Then choose Network from Control Panel and choose Binding to redo the binding. If the problem still occurs, remove the recently installed network components, restart the computer, and reinstall the network components.
