Reset Network Connectivity Batch Script in Windows

Windows CMD batch script designed to reset network connectivity

codez:

@echo on

ipconfig /release "interwebs"
ipconfig /renew "interwebs"

arp -d *

nbtstat -R
nbtstat -RR

ipconfig /flushdns
ipconfig /registerdns

timeout /t 10

netsh interface set interface "interwebs" DISABLED

timeout /t 10

netsh interface set interface "interwebs" ENABLED

The provided code sequence consists of several commands that are typically used for network-related operations in a Windows command prompt. Let's break down each line:

1. pconfig /release "interwebs": This command releases the IP address lease for the specified network interface called "interwebs." It essentially disconnects the interface from the network.

2. ipconfig /renew "interwebs": This command renews the IP address lease for the "interwebs" interface, attempting to reconnect it to the network.

3. arp -d *: This command clears the ARP (Address Resolution Protocol) cache, which is used for mapping IP addresses to physical MAC addresses.

4. nbtstat -R: This command purges and reloads the NetBIOS name cache, which stores name resolution information for NetBIOS names.

5. nbtstat -RR: This command releases and refreshes the NetBIOS names registered by the computer with WINS (Windows Internet Name Service) servers.

6. ipconfig /flushdns: This command flushes the DNS (Domain Name System) resolver cache, clearing any cached DNS entries.

7. ipconfig /registerdns: This command forces the computer to re-register its DNS records with the DNS server.

8. timeout /t 10: This command pauses the script execution for 10 seconds before proceeding to the next command. It provides a delay in the script.

9. netsh interface set interface "interwebs" DISABLED: This command disables the network interface called "interwebs," effectively disconnecting it from the network.

10. timeout /t 10: Another 10-second delay before the next command.

11. netsh interface set interface "interwebs" ENABLED: This command enables the previously disabled "interwebs" network interface, allowing it to reconnect to the network.

In summary, this code sequence performs a series of network-related operations such as releasing and renewing IP address leases, clearing caches, flushing DNS entries, disabling and re-enabling network interfaces, with some delays in between each step.
