If you are on a network, like at work, then it's possible that someone set their network protocols to match your protocols. For example:

A Network has an IP address of 111.22.333.xx. (not a true value, this is just an example) Each machine will need it's own IP address to connect to the network so the xx value needs to be unique. Usually the server is .01 then the next computer is .02, next one .03 and so on. Someone may have changed that value on their computer to the same one as yours.

Now if this happens at home when you are connecting to the internet, you need to contact the ISP because they should not have given you or anyone else the same IP address.

Are you running a home network, or is it just a single machine.

 

[no1stuna135]

home network, and it just randomly happened. ive had a network for like 3 years or so first time this has popped up

You might want to check for spyware/trojans to see if anyone is hacking to your network. Also check your IPs to make sure the computers have not been changed.

Are these IPs Staticly assigned, or dynamicly. If its static, then check and make sure that none have the same IP, if its dynamic, then try pulling the plug, and putting it back in (Ethernet). That should force it to reassign your adress.

Are you running this through Internet Gateway forwarding, or through a seperate router?

P.S. A firewall is a VERY good idea.

 

[no1stuna135]

dont routers come with firewalls?
ill run the scan then unplug and replug all the wires

 

[Whiteskin]

Yes. But i was not sure if you were using one. Can you configure your router to give certain ip's to certain ports? Sounds as if somthing changed in that area.

 

[no1stuna135]

i think i got it fixed, the thing hasnt popped up, all i did was unplug the router and replug it in.
thanks for the help

 

[Whiteskin]

Cool. Sounds good then.

a software fireall blocks outgoing connections. A hardware firewall blocks incoming. I'd suggest both.

Sygate's what I use, but for an easily (and widely recommended firewall) use ZoneAlarm. Both links are to freeware editons of these firewalls.
