Windows 7: Network problem

Network problem

ok sorry, but this is CRAZY!

i've been hammering this computer for hours now n still no internet..

ok here's the story:

i got 3 computers with on-board dual-LAN..
comp1 is running WinXP, i connected a cablemodem to it n it now has internet..
comp2 is running Win7, i connected an ethernet cable between comp1 n comp2..
then i ran the Network Setup Wizard on comp1 (where u tell it that this PC is connected directly to the internet n other PC's will be connecting to the internet thru this PC bla bla bla, etc.)
comp2 now has internet..
comp3 is also running Win7, tried to repeat last step but it doesnt work..

i figured this would be a cake-walk since i had no problem setting up comp1+comp2..
im guessing the reason i had no problems before was because i was dealing with WinXP+Win7.. but now that comp2+comp3 is about Win7+Win7 the story seems to be slightly different..

i've been all up n down in this #$/&"$%&$%5, tried everything on my bag of tricks but cant seem to get a connection.. im stuck with ip169..

has anybody been thru this process before?

Windows 7 Ult, Windows 8.1 Pro,

Here's a checklist of things for ICS and file sharing for 2 croslinked computers (in my case a Windows 7 and XP one):

- both computers set to the same workgroup
- restarts
- advanced sharing settings - all things turned on (network discovery etc.) except for password protected sharing
- bridged the connection with the internet
- turned on Internet Connection Sharing for the internet connection - this forced an ip to the other connection ( and gave an option to select which connection should have access to the ICS (the second connection or the bridge - you choose the second / crosslinked cable connection)
- shared some folders on both computers
- worked instantly (the other pc aquired a correct ip and internet)

Using ICS (Internet Connection Sharing)

Notice how in the link above they use a switch to connect more than one computer to the ICS machine.

The way you are doing it may not work correctly because you are daisy chaining the ICS machines end to end.

its working!
u the man chev!

yes, this is the way i thought i'd go about it since all these 3 puters got on-board dual-gigabit LAN..

i still need to go back n refine the configuration since i turned on a whole bunch of options in case one of them was causing the ip169, but apparently all i had to do was to activate the Bridged Connection option..

still im wondering if i really had to do this, cuz when i linked pc1+pc2 i didnt have to Bridge.. or maybe im wrong n this was it n i couldnt repeat the pc1+pc2 method for pc2+pc3 since pc1 connects directly to the internet n as far as pc3 is concerned pc2 doesnt connect directly to the internet..

anyways, thx a bunch

Bridging those connections allows the host machines to become the DHCP server. After that using a switch allows the DHCP host to give addresses out to the other machines. This will be the most reliable way.

hmm, since i started this here i should mention somethin' else:

one thing i love about Win7 is that when the network fails u can just go click on the red X for it to go check out whats goin' on n automatically fix it..
but what happens to me somewhat often is, when i start up the computer (or even just reboot) i get that red X over the network.. also clickin' it wont fix it, keeps sayin' a cable is unplugged.. so i have to go disable/enable the NIC n only then click on the red X to have a connection again..
this is very annoying, specially on the computer i only access remotely..
could this be due to all my computers have on-board dual-LAN?
