Having just removed a bunch of spyware and other junk from my friends computer, I thought everything was fine until I tried to connect to the net and got the error "windows cannot renew the IP address"
I have tried ipconfig /release, ipconfig /renew but that didn't work. The computer is running Windows XP S3, and is connecting through a bt home hub.
Any ideas would be greatly appreciated.

Sorry. Not sure what you mean by a "BT" home hub.

Is the hub then connected to your DSL\Cable modem?

a BT Home Hub is a wireless router BT provide for its customers ;)

Go to start, control panel, network and internet conections then go to network connections. Right click on the device you are using to connect to the BT Home Hub eg. Local Area Connection and select proprties.

Go to Internet protocol (TCP/IP) and make sure both options are set to automatic.

reboot your PC and BT home hub.

Sounds like the TCP IP stack may have been damaged.

My suggestion would be to post first in the "Am I infected? What do I do?" forum. Just to be 100% sure the PC is clean and that that is no longer the problem.

There is a tool that may repair the stack problem. The downside is it can also create further problems.

Good find. Not the program I had in mind. My idea involved 3rd party software.

@ pyke999. Did the netsh cmd fix the problem?

Thanks for the advice so far. I have already checked my tcp/ip settings and they are both set to auto. I will try the info in the support link, tomorrow and I'll let you know.
Thanks

hiya 999, reset your usb or ethernet
usb reinstall it again then set up the SSID and network keys
ethernet check BIOS see if it got kicked out by your virus

The hub works fine. I am able to connect through the hub with my laptop no trouble at all. So I am fairly sure that the problem lies with the pc itself.
Another forum I have looked at says the an ip starting 169 indicates that the system cannot update DNS, but it doesn't give any help from there.
Any ideas anyone??

Have you tried flushing your DNS cache?

Start\run\ type in cmd At the flashing prompt type in ipconfig /flushdns

Note the space between ipconfig and the /.
