There is an IP address conflict with another system on the network
Or the following Message saying ” This IP address is already in use on the network. Please reconfigure a different IP address”
This happens when you have two computers on same LAN Network gets same IP Address. When ever this problem comes then one of the computer is unable to connect to the computer network and gives the error.
Well this problem comes rarely but there can be following reasons of this error.
- Two PC’s are assigned the same static IP addresses
- One of the computer is assigned a static or fix IP address that falls into the DHCP (Dynamic Host Configuration Protocol) range for the local network and the same address is assigned to a computer by the DHCP server.
- Or if a laptop is put into sleep mode and then turned on while connected to another network that uses the same IP address
- if you have installed multiple network adapters, it is possible for a to have an IP address conflict with itself (self killing)

How to resolve an IP address conflict
Here are few techniques with which you can fix this problem.
1. Click Renew IP Address – You can renew and release the IP address for your computer by right clicking the Network Icons on right side of your taskbar and click Repair. or Simply go to network settings, disable enable the Wireless or Wired LAN Card.
2. Check Static IP Address – If your computer is on a static IP address, it is best to try and use a different one in the same subnet. One way to check to make sure the one you are picking is not already being used is to simple ping the IP address for example (ping 192.168.0.100).
3. DHCP – If you don’t need to use a static IP address, it’s best to simply choose DHCP instead of manually configuring the IP address. The server will deal what IP address to assign to your computer.
4. firmware Faults – In some rare instances, the actual DHCP server can malfunction and assign more than one computer the same IP. In this case, it is best to try and update the firmware on your router.
5. Change your Router and LAN Adopter (Rarely required to do this, just incase you have done all above)
6. You DSL Router and Your WiFi device both connected to each other and both are setup to give IP address via their DHCP, in that case you are using two DHCP servers, which will create Problem. in a Network you should use only one DHCP server which can Assign IP addresses without conflict. This sort of problem only occurs when you have two routers.
