netsh

Network Shell Configuration Utility

What Does It Do?

The netsh (Network Shell) command is a powerful scripting utility that lets you view and change almost every network setting on your Windows computer. Think of it as a Swiss Army knife for network configuration.

You can use it to configure network interfaces, manage WiFi settings, control firewall rules, reset network settings, and much more. It's particularly useful for advanced troubleshooting and network management tasks.

Administrator Privileges Required

Many netsh commands (like netsh int ip reset, netsh winsock reset, and firewall modifications) require Administrator privileges to run.

To run commands as Administrator in the simulator:

runas /user:administrator cmd

Request administrator privileges

Enter the password when prompted

netsh int ip reset

Now you can run netsh commands that require admin

Real Windows: Right-click Command Prompt and select "Run as administrator" before running these commands.
