If you open the properties of a network interface connection and then click to clear a check box (such as the Network Monitor Driver or the File and Printer Sharing check box) and then click to select the same check box, the change may appear to work as expected after you click OK. However, you may not be able to connect to a network resource.

Note To change the properties of a network interface connection, follow these steps:
  1. Click Start, and then click Control Panel.
  2. Click Network and Internet Connections.
  3. Click Network Connections.
  4. Right-click the network connection you want to change, and then click Properties.
This problem may occur if you are a member of both the Administrators group and the Network Configuration Operators group.
