When you upgrade a computer that is running Windows 95, Windows 98, or Windows Millennium Edition (Me) to Windows XP, you may lose statically configured network-specific settings (Internet Protocol [IP] address, shared or private network adapter status that uses Internet Connection Sharing [ICS], Microsoft Windows Internet Naming Service [WINS] servers, and so on). This may cause a loss of network connectivity or services after you upgrade to Windows XP.


This problem can occur when you install and configure multiple, duplicate network adapters before you upgrade to Windows XP. Duplicate adapters include any adapters with identical Plug-and-Play identification (ID) numbers. This usually occurs when two network adapters of the same manufacturer and model are installed on your computer.


To resolve this problem, set up ICS again or manually re-apply the network settings that were present before the upgrade in network properties for the connection. You can do this manually or by using the Network Setup Wizard after you finish the upgrade to Windows XP.

For more information about ICS, click Start, click Help and Support, type ICS in the Search box, and then view the topic about which you are interested.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
