Ok this has been happening all night and i searched online and couln't find anything so I thought someone else may have had the same problem.

Every couple minutes a little window pops up that says "Windows System Error- There is an IP address conflict with another system on the network"

Any ideas on hwo to fix it?

Are you on a "network"?

Yeah, with three other computers. We have restarted all four and have done a virus scan on all of them

it might have something to do with the workgroup, or the computer name. if two computers share the same name, you might get that error.

Maybe that will solve it. Do all have the same error message?

are you using a router to network them?

Yeah we are using a router. And we are all getting the same message

ok. well, I know for my network, the router assigns each computer its own IP address. I was looking in Start/settings/network connections ... Local Area Connection/status... it says my address is assigned by DHCP (some dynamic protocol). do all of your computers share 1 IP address?

It says shared...

but now all the other computers in the house are off and mine still isn't working

ok. they're all sharing 1 IP address? I'm going to paste from Windows XP help. I think the problem is - if you're using like a cable modem or DSL, you're not suppose to have it on more then 1 computer. If your router doesn't have its own DHCP protocol, to create dynamic IP address for each computer, you run into this problem. Are you sure you're using a router? or are you using a hub? I don't think they are the same thing. I think you either need a router or you need to pay extra to put the internet on all 4 computers (so you can have 4 IP addresses)

Using DHCP with Internet Connection Sharing

TCP/IP requires that each computer on a network have a unique number called an IP address. If you have two network adapters on your computer, each must have a different IP address. For example, when you connect to the Internet, your DSL or cable modem will have a different IP address than the network adapter connected to your home or small office network.

IP numbers are hierarchical. A number called a subnet mask is used with the IP address to enable the segmentation of a large network into smaller networks. It is important for you to remember the specific set of numbers used in your home network.

There are groups of IP addresses specifically reserved for small networks. One of these groups is used by residential gateways and by Internet Connection Sharing (ICS) - 192.168.0.x where x represents a number between 0 and 255.

These numbers are used with a subnet mask of 255.255.255.0. This particular subnet mask is known as a Class C subnet.

Understanding the IP addressing scheme and using it appropriately can be difficult. Residential gateways and Internet Connection Sharing (ICS) automate the IP numbering task for the ICS client computers on your network by using the Dynamic Host Configuration Protocol (DHCP) service. The DHCP service enables the residential gateway or the ICS host computer to assign IP addresses to client computers automatically. By default, when a residential gateway or ICS is installed, the DHCP service begins supplying addresses to computers on the network.

Your Internet service provider (ISP) might use a DHCP service to assign your computer an IP address when you connect to the Internet. This is commonly referred to as a dynamic IP address. Each time your computer connects to the Internet, a different but unique number might be assigned to it.

When you install ICS, assuming that you have two adapters in the computer—one for the device connecting you to the Internet and another for connecting to your home or small office network - an IP address of 192.168.0.1 is assigned to the network adapter connected to your home network. This is assigned permanently and is referred to as a static IP address because it does not change. Next, the DHCP service is loaded into memory so that IP addresses can be assigned to computers on the network.

Each client computer must request an address. It is important that the ICS host computer remain on all the time or be started prior to starting the other computers on your network. Otherwise, the client computers will be unable to obtain an IP address.

Note Your ISP might charge you for connecting multiple computers through a single Internet connection. Refer to your ISP for details.

hmm...we should all have different ones.

The weird thing is we have had this router for over a year and a week ago was the first time this ever happened.

I am about to give up.

did the router come with software to install? It might need an update w/ like its firmware or something.
