netsh int ip reset

Reset your TCP/IP stack to default to fix stubborn network problems.

netsh int ip reset

Command: netsh int ip reset

Category: Network

Type: CMD

Purpose

Resets the TCP/IP (Transmission Control Protocol/Internet Protocol) stack to its default installation state. This powerful command can fix deep network issues caused by corrupted network settings, malware modifications, or misconfigured network parameters.

Quick Summary

When network troubleshooting steps fail and connectivity issues persist, resetting the TCP/IP stack often resolves stubborn problems. This command rebuilds the entire network configuration to factory defaults, clearing corrupted settings that prevent network communication. Essential for fixing persistent network issues that other methods can't resolve.

How to Use

Open Command Prompt as Administrator.
Type netsh int ip reset and press Enter.
Alternatively, create a reset log: netsh int ip reset resetlog.txt
Restart your computer for changes to take full effect.
Reconfigure any custom network settings after restart.

Full syntax:

netsh int ip reset [log_file_path]

Tips and Best Practices

Always backup network settings before resetting (note custom IPs, DNS servers, etc.).
Requires administrator privileges - Must run as Administrator.
Restart is required - Changes don't fully apply until you reboot.
Reconfigure custom settings - Static IPs, custom DNS, etc. will be lost.
Save a reset log - Use resetlog.txt parameter to document what was changed.
Last resort tool - Try simpler fixes first (flushdns, release/renew, adapter restart).
Consider resetting Winsock catalog too: netsh winsock reset

Common Use Cases

Persistent connectivity issues: Can't connect to internet despite working hardware.
Corrupt network stack: Error messages about network configuration.
After malware removal: Malware modified network settings.
Failed network updates: Windows updates corrupted network configuration.
"No internet access" - Shows connected but no internet, even with working router.
IP configuration errors: Repeated DHCP or IP configuration failures.
Before clean Windows install: Nuclear option when nothing else works.

Prerequisites

Administrator rights required (mandatory)
Windows Command Prompt or PowerShell
Available on Windows XP and later
Important: Be ready to reconfigure network settings after restart
Document any custom network settings before running

What Gets Reset

This command resets:

IP address configuration to DHCP
DNS server addresses to automatic
All TCP/IP registry settings
Network adapter TCP/IP bindings
IP routing tables
IPsec policies related to IP

This command does NOT affect:

Physical network adapter drivers
Network adapter hardware settings
Wi-Fi passwords or connection profiles
Firewall rules
Network shares or mapped drives

Complete Network Reset Sequence

For maximum effectiveness, perform these steps in order:

Document current settings:
```
ipconfig /all > network-backup.txt
```
Reset Winsock Catalog:
```
netsh winsock reset
```
Reset TCP/IP Stack:
```
netsh int ip reset resetlog.txt
```
Reset Windows Firewall (optional):
```
netsh advfirewall reset
```
Flush DNS:
```
ipconfig /flushdns
```
Release and renew IP:
```
ipconfig /release
ipconfig /renew
```
Restart computer

Troubleshooting

"Access denied" - Must run Command Prompt as Administrator.
"The requested operation requires elevation" - Same as above; use "Run as administrator."
Still have problems after reset - Also run netsh winsock reset and restart.
Lost custom settings - Reconfigure static IP, DNS servers, etc. after restart.
Network adapter not working - Update or reinstall network adapter drivers.
Multiple adapters confused - Disable unused network adapters in Device Manager.

After Running the Command

Reconfigure these settings if you had custom configuration:

Static IP address:
- Open Network Connections
- Right-click adapter > Properties
- IPv4 > Properties
- Enter IP, subnet, gateway
Custom DNS servers:
- Same location as above
- Enter preferred and alternate DNS servers
- Example: Google DNS (8.8.8.8, 8.8.4.4) or Cloudflare (1.1.1.1)
VPN connections:
- Reconnect VPN
- May need to reconfigure VPN client
Proxy settings:
- Reconfigure if using proxy server
- Settings > Network & Internet > Proxy

Reset Winsock Catalog (run with TCP/IP reset):

netsh winsock reset

Reset Windows Firewall:

netsh advfirewall reset

Reset IPv6:

netsh interface ipv6 reset

Reset all network components (comprehensive):

netsh winsock reset
netsh int ip reset
netsh advfirewall reset
ipconfig /flushdns
ipconfig /release
ipconfig /renew

When to Use vs. Other Methods

Use TCP/IP reset when:

Simple troubleshooting didn't work (ipconfig release/renew, etc.)
Network stack is corrupted
After removing malware
Persistent "limited connectivity" issues
No internet despite proper configuration

Try these first before resetting:

Restart router and modem
ipconfig /release and ipconfig /renew
ipconfig /flushdns
Restart network adapter
Update network drivers
Run Network Troubleshooter

Understanding the Reset Log

If you specify a log file path:

netsh int ip reset resetlog.txt

The log contains:

Registry keys that were reset
Values that were changed
Timestamp of reset operation
Success/failure status

Review this log if you need to know exactly what was changed.

PowerShell Alternative

For PowerShell users:

# Reset TCP/IP
netsh int ip reset

# Or use PowerShell cmdlets:
Remove-NetIPAddress -Confirm:$false
Remove-NetRoute -Confirm:$false

netsh winsock reset - Reset Winsock catalog
ipconfig /release - Release IP address
ipconfig /renew - Renew IP address
ipconfig /flushdns - Clear DNS cache
Network Troubleshooter - Windows built-in troubleshooter
Get-NetAdapter (PowerShell) - View network adapter status
