Why does my computer restart when I restart the DHCP service?

If your computer is not working properly while you are working on it, it could be a problem with device drivers, hardware or software. \nDetailed instructions at http://tinyurl.com/yk5zpr

Looks like it's failing to get an IP address from DHCP server from your ISP or from router if connected to router.  Try restarting the router once and see.

Go to Start>Run and enter "CMD" to get to a command (DOS) prompt.  In the DOS prompt, type this:\n\nnetsh winsock reset catalog [[For Winsock, fixes most problems]]\n\nnetsh int ip reset resetlog.txt [[For TCP/IP]]\n\nThis will restore all network standards to the factory default.  If done properly, it will prompt you to restart your computer.\n\nGood luck!

It means that your router has assigned the same IP address to two computers.  As the router usually keeps the same IP for a week, you can still have a conflict even if the other PC is off, because it is still in the router list of IPs.\n\nGo to each of your computer, from the start button select run, and in the window that opens type ipconfig /release.  This will clear all the computers from your routers list.  Then go back and type ipconfig /renew and they should each get a new address.  The IP address for each wil display when you do the renew so you can confirm that they are each unique.

Do you have encryption set on your router? Have you input the encryption key into your laptop? You can try to disable the LAN connection, as well as the wireless, then re-enable the wireless and see if your IP renews. And does it show that you have a signal within range on the laptop?

Restart everything in your network. That sometimes solves the issue.

DHCP dynamically assigns an IP address to your computer when it's connected to the network, so you don't have to specify an static IP address as configuration.

This is going to sound dumb, but have you restarted the router?  Maybe the DHCP daemon got hung up and it just needs a reboot.  Other than that...is it possible for a 3rd machine to obtain an IP via DHCP from the wireless router?\n\nIf more than one machine is having an issue obtaining an IP then I would have to look at what is in common, the DHCP service on the wireless.\n\nWhat about assigning static IP's?  you could just set everything up with a static IP, set your wireless to not hand out DHCP and that might work.  Remember the default gateway will be the wireless router and you will need to know if the router handles DNS or if you have to supply a 3rd party DNS IP.

There could be a lot of reasons.  Try turning off your router for 30 seconds then turning back on.  Sometimes the ports won't release and become bogged down with traffic.

keep logs of your ip changing. plug in your modem, log your ip, turn it off tfor 60 second (no less) do it again.\n\nyou might have configured your modem wrong.

Check the modem to see if there are still any DHCP address left for it to hand out. Check if the DHCP server can hand out IP addresses to the wired computers, not just to the wireless computers.\nCheck if you can have both a wireless and a wired connection at the same time (some modems will only allow one type of connection). Check if your network card is installed properly. Check if the cable is still good, swap it with a different cable if you can.

I have been building/fixing computers for years and I have never heard of this program. I just did a search for it and all the searches are indicating that it is from a foreign country ie. Japan. I would stop it and see what happens, then restart your computer and see if it reloads itself. If you can stop it without anything negatively happening to your computer I would check your startup log and look for it there and terminate the services.\n\nType this in to your Run command: msconfig  if you can find it remove the checkmark next to the command line.

restart your computer.

It could be a 'wake on lan' event.  Depending on your computer, OS, and network adapter, search for that to find out how to switch it off.

You need to unplug the cable modem power for 30 seconds and plug it back in to let it reset after you change computers.  I just found that out from trial and error, while I was hooking up to my laptop.  On the laptop I had to restart the computer also, but on the desktop I didn't have to.  I think I am going to buy a wireless router next.

if you are running Windows ME, this has, and continues to be a problem. agreed to running it in safe mode, there is no way to stop some of the services running in regular mode, and it can take a LONG time to finnish a de-frag, as it starts-over each time, but it gets farther and farther each time.\n\nHope this helps !

If you want you dns to be static, then uncheck automatically assign dns in your network connections.  To flush the dns use, ipconfig /flushdns
