How do you troubleshoot and resolve network connectivity issues on a Windows server?

To troubleshoot and resolve network connectivity issues on a Windows server, follow these steps:

1. Check Physical Connections: Ensure that all network cables are properly connected and there are no physical damages to the cables or ports.

2. Verify IP Configuration: Check the IP address, subnet mask, gateway, and DNS settings of the server to ensure they are configured correctly.

3. Use Ping Command: Use the "ping" command to test connectivity to other devices on the network. If the server is unable to ping other devices, there may be a network issue.

4. Check Firewall Settings: Make sure that the server’s firewall is not blocking incoming or outgoing traffic that is required for network connectivity.

5. Restart Network Services: Restart the network adapter or services on the server to refresh the network connection.

6. Update Network Drivers: Ensure that the network adapter drivers are up-to-date to avoid any compatibility issues.

7. Use Network Troubleshooting Tools: Utilize built-in Windows network troubleshooting tools like Network and Sharing Center to diagnose and fix network connectivity issues.

By following these steps, you can effectively troubleshoot and resolve network connectivity issues on a Windows server.
