Both pc's can file share and are running win xp pro.
My pc is the one that directly connects to the net the wife's SHOULD connect through mine.

We both have zone alarm pro mine is set up to be the gateway and the wifes to connect through the gateway. This is all set up how the zone alarm help file suggest.
E.g (my ip is and the wife's is and both are subnet each ip and subnet are in the trusted zone of each others comp Not real IP's )

When I connect to the net on my comp the lan and modem connection icons pop up in her task bar.

This should mean she is connected to the lan and internet. Yes?
NO... well she can access my files but when she click IE it cannot find any webpages or servers. I clicked Internet Options> Connections Tab and clicked the Lan button and I've tried Auto detect settings Ticked and unticked and still no webpages.

BTW my modem in the connections is Connected & Shared

under ICS, I have:-
1, allowed other users to connect through this computers internet connection.

2, Establish a dial up connection....

3, Allow other network users....

Any suggestions LM? Any other network guru's?

It sounds as if you are connected fine, but that IE is the problem now ...

Does WinXP have a ping utility? If so, use it to ping a known IP and see what you get. If there is no ping utility, get one from the net (Google search (http://www.google.com/search?q=ping+utility+windows+xp)). If you get a connection, then the problem is definitely with IE and you can go from there.

Thanks LM ;) I'll try it in the morning. This is a strange one:confused:

Sounds like a setup problem with internet sharing, TCP/IP properties (gateway), or whatever. It should not be IE that does the pinging. Go into a DOS or command prompt and ping away. When that works, IE should work.

As I have said before, I recommend a router-switch. Each computer is equal in that arrangement, it is always on, and there is no problem setting it up, with the Linksys at least.

These are just guesses:

-- Start -> Settings -> Control Panel -> Internet Options -> Connections -> LAN settings. Do you need to setup her IE so it will use the proxy (your Zone Alarm on your machine)?

-- Start -> Settings -> Network & Dial-Up Connections -> Local Area Connection properties -> TCP/IP properties -> Advanced. Do you need to define a default gateway on her machine (to yours)?

I've never gotten into using ICS. It means you have to leave the boundary computer always power on for everyone else to get Internet access. According to http://support.microsoft.com/default.aspx?scid=kb;en-us;310563, "the computer must have two network connections present. One network adapter configured to connect to the internal home or small office network, and another connection using a 56K modem, ISDN, DSL, or cable modem to connect the small home or office network to the Internet." So you need a network card for your local network and something else for the Internet connection (analog modem, cable modem, DSL modem, etc.). Your computer needs to be the gateway or boundary host. You can't have the cable modem connected to a switch and then connect all your computers to the switch. According to this KB article, you have some setting up to do on your wife's computer.

I thought enabling ICS on the boundary host also created a diskette that you could use on each of the other intranet hosts to easily set them up instead of having to wade through all the TCP/IP setup. (http://www.microsoft.com/windowsxp/home/using/productdoc/en/hnw_create_network_setup_disk.asp)

If you are using Zone Alarm, is the Windows XP ICF (Internet Connection Firewall) disabled? (http://support.microsoft.com/default.aspx?scid=kb;EN-US;283673)

PPPoE = acronym for Point-to-Point Protocol over Ethernet. PPPoE relies on two widely accepted standards: PPP and Ethernet. PPPoE is a specification for connecting the users on an Ethernet to the Internet through a common broadband medium, such as a single DSL line, wireless device or cable modem. All the users over the Ethernet share a common connection, so the Ethernet principles supporting multiple users in a LAN combine with the principles of PPP, which apply to serial connections. (From http://www.webopedia.com/TERM/P/PPPoE.html.)

While your host is using just PPP with your modem, your wife might have to PPPoE from her host through yours since she is getting to yours over the Ethernet (LAN). Check http://support.microsoft.com/default.aspx?scid=kb;en-us;319661 which says to get WinXP SP1 or do a registry hack.

Hopefully you are not stuck with using AOL as your ISP. They use their 3rd party dialer software. Read http://support.microsoft.com/default.aspx?scid=kb;en-us;321644 which says you cannot use ICS with AOL up to and including version 7. I don't know about AOL 8.0, but it it still relies on their 3rd party dialer (and a dummy connectoid for it) then you need to get another ISP for ICS to work.
