open up Network Connections, under Control Panel.
Right click on your network adapter and click on Properties.
Click on Internet Protocol (TCP/IP), then click on Properties.
Click on Advanced, and click on the WINS tab.
Even if it is set to Default, set the radio button to Enable NetBIOS over TCP/IP.

Go back to the Services window and find the service named Routing and Remote Access.
