Setting Up a VPN Connection

The ncpa.cpl command also allows you to set up VPN connections:

1. Click on “File” in the Network Connections folder
2. Select “New Incoming Connection” or “New Outgoing Connection”
3. Follow the wizard to set up your VPN

Configuring DNS and WINS Servers

Domain Name System (DNS) and Windows Internet Name Service (WINS) servers are crucial for resolving hostnames to IP addresses:

1. In the network properties, find the Internet Protocol Version 4 (TCP/IPv4) or Version 6 (TCP/IPv6) settings.
2. Click Properties and enter your preferred DNS and WINS server addresses.

Correctly configuring these servers ensures that your network can properly resolve hostnames, leading to faster and more reliable connections.

Setting Up a New Network Connection

There may be times when you need to set up a new network connection, whether it’s a new Ethernet connection or a VPN.

Creating a New Connection

To set up a new Ethernet or Wi-Fi connection:

1. Open the Network Connections window using ncpa.cpl.
2. Click Set up a new connection or network in the Network and Sharing Center.
