BleepingComputer.com: Windows system error

"There is an IP conflict with another system on the network."

Am I being hijacked? Is this a problem? Something that I need to
address?

Thanks,

Need some more info.

How many computers are on your network? What operating systems are they. How are they connected. Wired, wireless, both?

i use windows xp pro. Main computer is wired to cable.
#2 is wireless,linksys wireless g 2.4 about 25 ft from main.
3rd is laptop, connected wireless, same way.

On the wireless machines have you enabled\set-up WPA? An explanation of WPA. If you have then we can move on to the next step. If not then I recommend that you do using the documentation received with the wireless device they connect to.

Are you in an environment where other people\neighbors may be close enough to pick-up your wireless signal. Apartment, small residential lots, etc?

Another machine is using the same ip address as yours. Maybe it's using static address. You need to find the machine out.

I suggest you use mac address filtering, since you only have 2 computers that use your connetion.
