I have a laptop connected just fine on my home wireless network. My desktop (wired) is another story. It was working fine and then just quit. If I run an ipconfig... it comes back with a 169. Number which means its not getting out to the network. I have turned off the firewall and all the TCP/IP settings are exactly the same as the laptop.

If I put a static IP address in the desktop, it will let me ping an ip address such as Yahoo, but it won't let me ping yahoo.com (or any name). But, if I switch back to a dynamic address, it just finds that 169.number.

I replaced the NIC and that didn't work. I have switched cables, etc and nothing is working. The laptop connects just fine. The desktop won't. I'm wondering if spyware or a virus has caused something to block the ip address from being assigned on the NIC.

Please help!

If you have Win XP you can try resetting the tcp/ip stack. This is the command (Start > Run, type in 'cmd', press Enter):
netsh int ip reset c:\resetlog.txt

That particular problem is caused by not having the correct DNS servers entered. You can find them by doing

Ipconfig /all

On your working machine, or by looking at your DHCP server's settings.

This is most likely a winsock problem. Have you just recently updated to sp2? If so try removing the sp2 and see if that does it. You may have some title that is not compatible with sp2.

And of course you could just wipe it. That fixes everything

According to my dsl provider I have to have the DNS settings to automatic. I did however pull the DNS settings out of the working laptop and put those into the desktop thinking, just like you, that that would fix the issue... it didn't. I still have the same problem.

Also, I have not installed SP2.

That only works if you use DHCP. If you go static IP, you will have to manually set the gateway and DNS servers.

Have try re-setting your router OR look into the host file in C:\WINDOWS\\system32\drivers\etc? Drag the host file in notepad and if you see any ip address under 127.0.01, remove it, save the host file, and re-boot. Otherwise, I agree with jcopeland, sp2 update or/and spyware may be blocking. Simply un-install sp2 if you have sp2 installed. And it's good to always have some sort of spyware killer on hand. I recommend the new Microsoft antispyware and ADWARESAFE (adwaresafe.com). Both will automatically scan your PC at the time you would like it to do so, unlike ad-aware or pestpatrol. MS antispyware will even remove them for you automatically, too as a bonus. Of course, the worst case is to format and re-install. If you do that, I highly recommend installing NORTON GOBACK the 1st thing after re-installing XP which will restore your PC any moment to the time when your PC work.

Unplug the router, then plug it back in. Finally, reboot the computer.

Just checking. Did you get this item resolved? The 169.254 problem can be a complex problem. Probably related to a corrupt TCP stack a/o Winsock error.

P2E

Just to clarify...

The post RE needing to enter DNS and Gateway information when using static IP addresses, you should enter the IP address of your router. The router obtains all the information from your DSL provider automatically, and should forward any DNS reqests to the automatically configured address. So just use the router's IP address for the Default Gateway and Primary DNS Server.
