Solved No IP address found

Specs: Windows XP Pro SP1, 2.8 GHz/0.99 GB
I recently reinstalled Windows and lost the internet connection. I have a cable connection and Vonage phone that uses it. The phone works perfectly, but the computer doesn't. I tried lots of different things, including bypassing the Vonage router; nothing works. When I try to search for the IP address, my computer comes up blank.

After reading other people's posts, I did a few operations:
1. Checked the TCPIP.sys file - there is only one of them in my computer, and it didn't seem damaged.
2. Ran the 'smc /scannow' command - nothing happened.
3. Tried to fix the registry with Winsockfix software - nothing changed.
4. Tried to enter the network settings manually - didn't work.
5. Reformatted the hard drive - didn't help.
Pinging requests come back empty, ip hosts are not found. Please help!

I have a good news - I reinstalled the ethernet controller driver last night and got the internet connection working! Next time I will definitely know what to do. Thank you all for your help!!!

command is sfc /scannow as in system file check scan now.

You just reinstalled windows so there is no need for most of what you did.

How long had this been working before you reinstalled XP?

Are the cables connected EXACTLY the same way they were BEFORE you reformatted?

What network settings did you try to enter manually?

I had no problem with my existing configuration for 4 years, bought the computer in 2005.

The cables are connected exactly the same way. I didn't even touch them when I reinstalled my Windows for the first time (that's when the problem started). After that, I checked and re-checked them many, many times, you can't even imagine... I see the back of my desk in my dreams already! :)

I tried entering the IP addresses manually (,, as was recommended in one of the posts on this site that I have read). But they didn't stick. The settings were changed back to default.

OK. In tcp/ip properties set to "obtain ip automatically", click on OK then restart your computer.

Then go Start/Run and type "cmd" without the ""s and hit enter.

In the black command box type "ipconfig /all" again without the ""s.

right mouse click on the top of the black box and select Edit and select all. Then again select edit and copy. You can now paste the ipconfig results into a post.

Though you would need to get this to a pc that does have internet access :-)

I have already done it many times. What I get is "Windows IP configuration" and nothing else. Absolutely nothing else. Just this one line. I also tried pinging everything possible, but get the message "no ip host found"...

I am writing to you from work now, I have internet connection here. So if you don't hear back in a few hours, that means that I am at home where I don't have access to the internet. But I really want to resolve this issue, so if you could be patient and help me over a period of a few days, it would be great... Thank you, I really appreciate your help!

You can't ping if you have no ip.

Is the network card installed in Device manager? No yellow exclaimation points?
what do you mean by "they didn't stick. The settings were changed back to default."? What is the default and you did click on the OK?

Did you set this up originally with the router? Perhaps calling vonage would help in determining if you are supposed to be doing dhcp or static and if static what the ip should be.

I will have to check the Device manager. The network card should be installed, because it was before I reinstalled the Windows - could it change?

"They didn't stick" means that after I rebooted the computer, the settings were back to "obtain IP automatically" which I think is a default setting. All the boxes for the IP addresses there are blank now, nothing is entered there. I did click on the "OK", but the changes didn't apply after the reboot.

When I was setting up my Vonage account about three and a half years ago, I didn't need to change any settings in my computer. I don't remember my IP being static ever on this computer. But I will call them today after I get home and find out for sure.

Do you want to give me some homework? I will talk to Vonage and check whether the network card is installed - is there anything else I can do with my computer that is of interest to you?

OK, thanks, I will try that - what should I see there? The problem is that I don't have the internet at home, and when I do whatever you tell me to, I have to wait until tomorrow to report back to you... So please give me as much information as possible. Thank you!

Having the nic physically is one thing. Having its driver loaded and working in xp is another. This is what we are checking on in Device manager.

If set to obtain ip automatically you should be getting a ip address.

Make sure the windows firewall is disabled though that doesn't come until SP2. You are on SP1.

If you go to a cmd prompt and type ipconfig /renew what error do you get?

Good suggestion from mavis007

Thanks, guys, I appreciate your help. I checked the firewall, disabled it myself (I had ZoneAlarm). There was no Windows Firewall.

When I type 'ipconfig /renew', I don't get anything besides the usual 'Windows IP configuration' and back to c.

Hi guys,

last night I discovered that an ethernet controller driver is missing on my computer. I just downloaded it from the Dell website, will install it later today at home and will let you know whether that was the problem. Vonage said that they don't use static IP addresses.

I also checked my network adapter - it's called '1394 Net Adapter'. It's installed, the driver for it is working and there are no conflicts associated with it. I suspect that the problem lies in the ethernet controller.

One trick I used to use when a pc will not bring up any ip at all is this:

1. Turn off your pc and disconnect ALL the cables from the front and back including the power cable.

2. Press and hold down the power button on the pc for 15-30 sec.

3. Reconnect all the cables back and restart your pc.

(If this is a laptop then take out the battery also in step one. )

Getting information off the Internet is like taking a drink from a fire hydrant.

Natasha A. the 1394 adapter is not your network card but is the firewire interface.

This is what I thought may be happening. It would appear you didn't install your ethernet card during your reinstall.

Let's get back to Device Manager and tell us under network adapters what is listed.

The only thing listed under "Network Adapters" on my computer is "1394 Net Adapter".
