Windows has detected an IP address conflict



If you are using fixed IP, then high chances are that two PCs were set to the same IP.

However, if you are using dynamic IP, the following describes a scenario for it.

There are two WiFi networks in the environment.

Network-1
Network-2

Workflow:

1.) PC-1 connected to Network-1 and received IP-1
2.) PC-2 connected to Network-2 and received IP-2
3.) Network-1 restarted
4.) PC-2 restarted
5.) PC-1 connected to Network-2 and received IP-3
6.) PC-2 connected to Network-1 and received IP-1
7.) PC-1 disconnected from Network-2 and connected to Network-1 and received IP-1 because it didn't restart itself --> IP conflict detected.

The solution is to disconnect PC-1 from Network-1 and reconnect again.

Note : It is not always true that this happens because someone is trying to hack you by mimicking the IP address of your PC - especially if you are home alone connected to your own routers.
