Consider the following scenario:

  • You configure several IP addresses on a network adapter on a computer that is running Windows Server 2008 or Windows Vista.
  • You modify some IP addresses by using Network Connections (Ncpa.cpl) or the Netsh.exe command-line tool. For example, you add, remove, or change some IP addresses.
  • One of the following actions occurs:
    • You restart the computer.
    • The network adapter is disabled and then re-enabled.

In this scenario, some other IP addresses on the network adapter are lost. This issue causes some network connectivity problems.
