When you disable and then re-enable the LAN-side network adapter on a Windows XP SP3-based computer that is configured as a Connection Sharing host, a client computer on the network cannot access the Internet
You are running a Windows XP Service Pack 3 (SP3)-based computer that has two network adapters installed.
You enable the Internet Connection Sharing feature, and then you configure the computer as a Connection Sharing host.
You connect another computer to the Connection Sharing network. This computer functions as a Connection Sharing client.
Note In this Connection Sharing network, one network adapter on the host computer is connected to the Internet, and the other network adapter is connected to a local area network (LAN).
You disable and then re-enable the LAN-side network adapter on the host computer.
In this scenario, the Connection Sharing client computer cannot access the Internet through the Connection Sharing network. If you try to use a tool such as Nslookup.exe to resolve the domain name on the client computer, the operation is unsuccessful. Additionally, you receive an error message that resembles the following:
DNS server is not responding.
Note If the LAN-side network adapter is a USB-based network adapter, the issue also occurs when you physically disconnect and then reconnect this network adapter.
