SYMPTOMS
Internet Connection Sharing (ICS) requires TCP/IP to be bound to the internal network adapter. If TCP/IP is not bound to the adapter connecting to the Internet and the adapter connecting to the LAN, the ICS host cannot function. The following items should appear in Network properties:
 * External Adapter (Dial-Up Adapter or Network Adapter)
 * Internal Adapter (Adapter connecting ICS to the LAN)
 * Internet Connection Sharing
 * Internet Connection Sharing (Protocol)->External Adapter
 * Internet Connection Sharing (Protocol)->Internal adapter
 * Internet Connection Sharing (Protocol)->Internet Connection Sharing
 * TCP/IP(Home)->Internal Adapter
 * TCP/IP(Shared)->External Adapter
 * TCP/IP->Internet Connection Sharing



CAUSE
Setup does not verify that TCP/IP is bound to the internal adapter. This is apparent only in the Winipcfg tool. If TCP/IP is bound correctly, Winipcfg lists two adapters: ICS Adapter and Internal Adapter.



RESOLUTION
To resolve this issue
 * 1) Click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.

 * 6) Next, click Add, click Protocol, click Microsoft, and then double-click TCP/IP.
 * 7) Verify that TCP/IP has been bound to both adapters. Click OK, and then restart the computer when you are prompted.
 * 8) Verify that your Internet connection works. Once this is verified, click Start, point to Settings, click Control Panel, and then double-click Add/Remove Programs.
 * 9) Click the Windows Setup tab.
 * 10) Double-click Internet Tools, and then click to select the Internet Connection Sharing check box. Click OK, and then click OK to start the ICS Setup Wizard.
