NIC Card not responding - no IP address

are you using a router or a modem?? because if you dont have IP address then your DHCP settings on your router/modem is not giving you an IP address at all... then it could be an ISP issue... usually even if the drivers on your NIC is not working properly you will still get an IP address that usually starts with 169.xx.xx.xx

 it is an IP address given by your PC.. since your getting a blank ip address and your NIC is working properly i do suggest borrow a modem from a friend or neighbor to test your internet connection... or you can ask your ISP to replace it your modem/router...

I am using a wireless DSL router/modem.  I don't believe the router is the problem because I have two Dell computers.  One runs just find, able to go online and do whatever I need.  The other one is the one with no IP address.

Thanks.

I have been away for a few weeks.  My problem is still unresolved.  Can anyone tell me how I can find an IP address? My modem/router is function just fine because I am using it with another desk top.  Is there any way around this problem?

Thanks for your help.

 did you reset your TC/IP setting???

open network connections..right click on the LAN. in the box that pops up scroll down to the Internet Protocol (TCP/IP) line ..click on it and then click on the properties button

In the General screen ensure the Obtain an IP address automatically box is checked

Also ensure that the Obtain DNS server address automatically is checked. Click the advanded button and in the settings box make sure it says DHCP enabled click ok to go to the first box. Click on the alternate configuration tab and make sure the Automatic private IP address line is checked.. click ok....

bring up the run command and type cmd.

In the dos box type ipconfig /all copy and paste the results here..

Thank you for answering my post.  My computer's TP/IP setting shows exactly what you have showing but when I ran the ipconfig/all I get this message:

An internal error occurred.

The request is not supported.

I checked the Network connection, it is connected (using ethernet cable) and the device is working properly under Device Status:

Local Area Connection4 

connected

Do you or anyone have any idea what this means?

Thank you for helping.

you did put a space between the g in config and  / correct?

Do the lights on the ethernet port on the computer Flash?

I found this by Googling your issue..seems to have worked for a couple of people :

Finally I did a file search for tcpip.sys and renamed every instance to "tcpip.sys_old" - essentially disabling it... Windows XP message came up immediately saying it needed to repair itself but I waited and proceeded to rename all instances of tcpip.sys found and then followed the instruction window and inserted my Windows XP disk and let it have its way with my computer... rebooted and wow! CONNECTION RE-ESTABLISHED all on its own. That is all I did.. no expert believe me, I have no clue why it worked, just used my imagination. ;-)

Something else....

Click START then RUN. You will then see a box to type in. Delete whatever in in there and type CMD. Then click OK.
Type in :-
netsh winsock reset
Then press ENTER and restart your computer.

Next, repeat the first part of the previous step.
(Click START then RUN. You will then see a box to type in. Delete whatever in in there and type CMD. Then click OK.)
Type in :-
netsh int ip reset c:\resetlog.txt
Then press ENTER and restart your computer again.

You should now be able to connect to your router.

I am happy to see that there is hope for my computer.  I only found one tcpop.sys file which I re-named just like you said.  After inserting the CD, there are five options and I don't know which one I should choose, so I am stuck:

1.  install Windows XP

2.  learn more about the setup process

3.  install optional windows components

4.  perform additional tasks

5.  check system compatibility

Next question:  If I were successful in re-establishing my IP address, do I need to do the two CMD in your instructions any way?

By the way, as far as I am concern, you are an expert.  Thank you for helping me out.

I believe you want # 4 and do a repair option..

You could alway rename the file again and try the 2nd option with the  command lines.. i belive you tcip stacks or winsocks are indeed messed up..

THANK YOU VERY MUCH!

I now have internet connection.  Can I delete the "tcpip.sys_old" file from my computer.

Next questions, who can I ask about viruses?  As soon as I got back into internet, AVG found a virus on my computer which might explain the lost internet connection in the first place.  the virus is in:

C:\WINDOWS\system32\colbactd.dll

Virus identified Obfustat.ADXW

Can you please direct me to the right place?

Thanks a million for your help.

Yes you should be able to delete the old file as a new one was created...

As to the AVG i run that too,  won't it clean it out for you?

If not is would suggest that you google the virus name and see if there are any (free) cleaners that need to be run....
