No default gateway after Windows Update

Hi!

I have a problem that I've been trying to solve for the last hour, unsuccessfully. After the latest Windows Update, I can no longer connect to the Internet. I've been looking through several answers, both here at Seven Forums, and at other places, but haven't found anything.

• Here's my problem:
• If I check ipconfig, the fields "Connection-specific DNS Suffix" and "Default gateway" are blank.
• The OS displays my network as "Unidentified network" and displays no access to anything (not even my computer to the LAN).
• I tried disabling the LAN-connection and re-enabling it, which worked the first time, but stopped working as soon as I put the computer to sleep or turned it off, and now it doesn't work again.
• The Windows Troubleshooter says "Local Area Connection doesn't have a valid IP Configuration" (which is quite understandable, see point 1).
• MSN Messenger gives Windows error code 80072ee7, but looking it up, it only applies to Windows Update, but I can't connect to the Internet at all (tried the fix anyway, but it didn't work).
  If anyone can give me some tips, I'd really appreciate it. Thanks!

Best regards,

Hi and thanks =) Yeah, I tried that... Didn't work. Have tried several restore points.

Seems I got it. The company where I work uses IP-phones, through which the computer is connected. There was something wrong with the configuration of my company phone, so bypassed it and it worked. Annoying error and I should have found it earlier... Anyway, the problem is solved. Thank you for your help!
