Cannot renew IP

[Frank]

I am suddenly not able to renew the IP address of one of
my two Windows XP computers on my home LAN. They are
both connected to a router with a DHCP server enabled.
The DHCP server works and assigns IP addresses to the
second computer.

ON the computer where it does not work, I click
on 'Repair' and get the error message: "The following
steps of the repair operation failed: Renewing the IP
address"

I have uninstalled and reinstalled the network device
drivers for the network cards; I have tried different
network cards.

There's no firewall running; I have confirmed that the
DHCP client service is running.

I have issued the NETSH INT IP RESET RESETLOG.TXT command
from the command prompt.

Nothing seems to work. I always end up with a
169.254.xx.xx address.

I have tried manually assigning an ip addres and
disabling the DHCP function of the router, but still no
network connectivity; that is, no LAN or internet.

I am at a total loss as to what the problem is.

Oh, I have also performed an 'upgrade' reinstallation of
windows xp pro from the source cd. Same result.

I've also done a virus scan w/ Norton, most recent sig
file.

Any help would be appreciated. Thank you.

Open a command prompt box, and use the command:

ipconfig /?

which will give you the options for this command.

Read about, and then consider issuing the command:

ipconfig /renew

and see if this does the trick.

Just afew suggestions which you may or may not have
already tried:
1. can you ping the router from the "faulty" machine
2. have you tied plugging it in to a different port on
the router (try the one that the other machine uses)
3. are you getting a link light on the router for the
port that you are using
4. reboot/ power cycle the router in case something is
sticking
5. is the faulty machine definitely set to receive an
address automatically
6 are there enough ip addresses on the DHCP scope
7 try a different cable (the one that the working machine
uses)

Have you tried swapping out the network cable? Have you tested another PC
plugged into the same router port?

I am having a similar problem after cleaning my pc of
adware and spyware programs that makes it almost
impossible to use internet explorer. I downloaded
Lavasoft Ad-WARE 6 to clean my pc and after the process
completes, I cannot signon onto the internet anymore. I
run ipconfig and get an IP address with 169.254.xx.xx. I
use Verizon DSL to connect and spoke with Tech Support but
we were not able to reset the IP address no matter what we
tried. I had to run system recovery to put the pc back
with all of this intrusion software. Also tried to
download Netscape 7.1 and it will not connect with an
error message, connection denied to 'info.netscape.com'.
If you found an answer, please post.

==========================================================================

It sounds to me that the spyware damaged your Winsock keys in the Registry.
Please try the following procedure for replacing the winsock and winsock2 registry keys:

 

Uninstall any third-party proxy software or firewall programs before proceeding.

 

Step 1: Delete registry keys

 

A)Open Regedit from the Run line
B)Go to both of the following keys, EXPORT each of them, and then delete them:
(To export a key, you right click on it and choose "export" - you can choose where to export them to -
DESKTOP is handy -
and you need to type in a file name such as "exported Winsock key"  /  "exported WinSock2 key"
and then click on SAVE)

 

HKLM\SYSTEM\CurrentControlSet\Services\Winsock
HKLM\SYSTEM\CurrentControlSet\Services\WinSock2
C)Restart the computer

 

NOTE: It is important to restart the computer after deleting the Winsock keys.
Doing so causes the XP operating system to recreate shell entries for those two
keys. If this is not done, the next step does not work correctly.

 

Step 2: Install TCP/IP on top of itself

 

A)Open the properties window of the network connection (Local Area Connection)
B)Click Install
C)Click Protocol, then Add
D)Click Have Disk
E)Type the path to the \%systemroot%\inf folder (usually C:\Windows\inf) and click OK
(if you try to click Browse, then browse to the \inf folder,
it may not show up in the list)
F)You should now see "Internet Protocol (TCP/IP)" in the list of available
protocols. Select it and click OK.
G)Restart the computer

 

When the computer reboots you will have functional Winsock keys.
If so, then be sure to delete the exported winsock and winsock2 reg files.
(You don't want to accidentally put them back in the registry)

 

Side effects and possible problems:

 

This method will restore basic functionality to the Winsock keys, but is not a
complete rebuild. On a default install of Windows XP the registry key:
HKLM\SYSTEM\CurrentControlSet\Services\Winsock2\
Parameters\Protocol_Catalog9\Catalog_Entries will have 11 sub-keys.
When applying this method, the Catalog_Entries will only have 3 sub-keys.
However, it works and there does not appear to be any side effects.
The missing entries relate back to the:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces key.
Also, third-party proxy software or firewalls will need to be reinstalled.
