Network bindings are incorrect after you change a network adapter’s configuration on a computer that is running Windows Vista or Windows Server 2008
Network bindings are incorrect after you change a network adapter’s configuration. For example, this can occur after you enable or disable a network adapter, or after you install or remove the driver for a network adapter. In some cases, all transports and filters are bound to each available miniport at the same time.
