Solution: Windows 7 ICS stopped working after a week

I have been sharing my cell phone tether connection for about a week over an ad hoc network and suddenly it stopped working. After banging my head against a wall for about an hour I finally figured out how to fix it and wanted to share.

  • Open Network and Sharing Center
  • Open the adapter that is connected to the internet and find it’s properties panel
  • Go to the sharing tab and disable sharing
  • Apply and close the properties panel
  • Go back to the Network and Sharing Center
  • Click set up a new connection or network
  • Set up a wireless ad hoc connection
  • Configure your new network
  • Enable ICS from this panel

If you do that it frees up whatever resource was being tied up and you can share your connection again.
