If you’ve done everything correctly, ICS should show this screen to indicate that it’s ready to go. Click OK to continue
Where is this thing?
You access ICS’ controls via the Internet Options Control panel. When ICS is installed, you’ll see the addition of a new Sharing button on this Control Panel as shown below.
Clicking on the Sharing button brings up the ICS Control Panel. As you can see below, there’s not a lot you can do. No control of logging, no ability to open special ports, no control over Client network access (other than to shut off ICS), no control over ICS’ DHCP server. (We suggest checking the “Show Icon in Taskbar” box so that you’ll be reminded that ICS is running and be able to easily access its Control Panel.)
Note the HELP button in the above screenshot. Clicking on it will bring up ICS help. You may find some useful information there, but I thought that most of it wasn’t much help. The Client machine setup information wasn’t much help and was confusing because it referred to the LINKLOCAL 169.254.X.X addresses, when ICS uses the 192.168.0.X series of address for the LAN.
Fortunately, Microsoft has a few helpful articles in its Knowledge Base that can help you figure out whether ICS has installed correctly. In particular, Q236465 – Description of How ICS Appears in Network Properties tells you what your Network Control Panel should look like after you install ICS. For links to other MS Knowledge Base articles, check the ICS Troubleshooting page. SOHOinter.net also has a ICS debugging page that tells you how to check ICS’ install logs.
Is this thing on?
You’re probably excited to get started sharing, so go ahead and try your browser on your sharing Client computers. If, however, things don’t work, you may want to see if ICS installed properly. Check for the following things on the computer where you installed ICS.
If you check out the Network Control Panel, you’ll see some new additions:
a new Internet Connection Sharing adapter
copies of a new Internet Connection Sharing protocol installed and bound to each of your Network adapters
a copy of TCP/IP installed and bound to the new Internet Connection Sharing adapter
the copy of TCP/IP that is bound to the adapter that you selected to Connect to the Internet in the ICS setup wizard will be marked with (Shared).
the copy of TCP/IP that is bound to the adapter that you selected to Connect to your home network in the ICS setup wizard will be marked with (Home).
Run winipcfg and you should find an ICSHARE adapter replacing your cable modem NIC as shown below. You should see the information assigned by your ISPs DHCP server. If you don’t, ICS isn’t set up properly. You can try clicking the Release then the Renew button to see if you can get a DHCP lease, but you’ll probably have to reinstall ICS to get things working.
Finally, bring up the Network Control Panel and check the Properties for the copy of TCP/IP that is bound to your LAN NIC. It should be assigned an IP of 192.168.0.1, with subnet mask 255.255.255.0
If your network settings don’t look like what is described above, try uninstalling and reinstalling ICS. Make sure you uninstall ICS via the Add/Remove Control Panel and not just by deleting the ICS adapters in the Network Control panel. If ICS still doesn’t work, you can try this procedure if you’re comfortable editing the Registry, or you can try reinstalling WinMe, then reinstalling ICS.
If after checking all this, you still can’t access the Internet from your other computers, you probably will need to check the TCP/IP and Internet application settings for your Client computers. Go to this page to do this.
Tip: Take another look at the ICS Control Panel above. You can specify a primary network adapter and a secondary network adapter! This feature lets you share the Internet connection with two different LAN segments! Go to this page to see how to do it.
