SYMPTOMS

On a computer that is running Windows Vista or Windows Server 2008, some IPv6 network adapters are unexpectedly reinstalled when any of the following events occurs:
  • You restart the computer
  • You resume the computer from sleep or hibernation
  • You restore network connectivity to the computer
Usually, this behavior does not cause significant issues. However, you may experience the following issues, depending on your specific configuration:
  • Performance on the computer may be noticeably reduced for a long time, and unnecessary network traffic may occur. This behavior may occur if your system is configured to install device drivers from a shared folder that hosts many device drivers.
  • The computer may stop responding (hangs) during system startup. This behavior occurs because the number of installed IPv6 network adapters grows too large over a long period of time.
