I just recently installed Windows 7 SP 1 on my computer. However it failed, and I rolled back the installation, only to now have an error with my ethernet port, saying that I cannot connect, for the stated reason.

How can I fix this? Without having to format my PC?

I have tried

  • Resetting Winsock
  • Flushing my DNS via ipconfig.
  • Disabled/ Enabled my network adapter.

This question came from our site for system and network administrators.

You need to tell us a little more about your network -- are you at home or at work? What do you know about your network connection outside your laptop? The Ethernet port is probably correct, but it cannot find a path to the wider world -- perhaps because of a local network configuration (like a proxy server you need to know about), or perhaps because of the Windows 7 security has been set up. – Johnnie Odom Apr 3 '11 at 21:53
This is a home network. I am running Windows 7 on my desktop computer. I am posting this comment from my laptop. – JCubed Apr 4 '11 at 6:47
This is a home network. I am running Windows 7 on my desktop computer. I am posting this comment from my laptop. I have never had to do this before, as it was all automatically handled. My router is a DGl-4300, and I just have a modem that comcast gave me. I tried rolling back my update, but I get a strange hex error. I know its an OS error, because my ethernet port works when I boot into ubuntu. Is this enough information? **edit – JCubed Apr 4 '11 at 7:51
Can you reinstall the ethernet drivers? – tjameson Apr 4 '11 at 16:49
Can you please try resetting your IE settings on Tools - Internet option - Advanced - Reset settings? – user107596 Dec 1 '11 at 4:29

I tried doing so. I uninstalled my ethernet drivers, I rebooted my machine, and still, I encountered the error. I'm just gonna take my chances with guessing that SP 1 borked my machine, and so I am reinstalling windows.
