Renewing IP address/Refreshing all DHCP leases : Repair operation fail

[Richiy]

Hey, my pc can't seem to connect to the internet, although the LAN settings say that it is enabled.

I get the error:

The following steps of the repair operation failed:
Renewing the IP address.
Refreshing all DHCP leases and re-registering DNS names.

Please contact your network administrator or ISP.

And when I try ipconfig /release, it says its already been released and when I try ipconfig /renew it says "An error occurred while renewing interface Local Area Connection : The system cannot find the file specified."

It worked fine for a few days. The only thing I did was uninstall Common Names Toolbar from my pc, and deleted the folder. It came up as spyware so I got rid of it. I don't know too much about PC's, any help would be great. Thanks in advance.

Common Names is known to shaft the TCP/IP stack. Remove TCP/IP completely and reinstall.

Ash.

Ahhh, I'm pretty sure this is the problem with my home network as well. I've tried everything else suggested for problems like this with no luck. Any ideas on how to remove and reinstall TCP/IP in Windows XP (as it won't let you uninstall it)? And an address of who to kill at CommonNames? Heh.

CommonNames it was. Downloaded and installed the toolbar from

http://www.CommonNames.com,

then unstalled it. Voila, net connection restored to perfect working order. Fortunately I hadn't tried formatting yet, but that was still a pain. Evil.
