Follow these steps to disable WLBS: NOTE: Cluster Adapter is the network interface card (NIC) used for cluster traffic; it is not the WLBS Virtual NIC adapter. 1. In Control Panal, double-click Network, and then click the Bindings tab. 2. Under "Show Bindings For", select "All Protocols". 3. Disable the binding from the WLBS driver protocol to the network adapter. 4. Disable the binding from the TCP/IP and WINS Client protocols to the WLBS Virtual NIC adapter. 5. If you are using multiple adapters and if you plan to use this adapter to handle TCP/IP and WINS Client traffic, enable the binding from the TCP/IP and WINS Client protocols to the cluster adapter. 6. Click OK to close the dialog box. 7. Restart the computer. To fully remove the WLBS software, follow these steps: 1. In Control Panal, double-click Network, and then click the Adapters tab. 2.
