Networking Guru Needed
<div class="IPBDescription">Help me I am ripping out hair</div> Yea, so anyways, when the phone company installed my DSL modem back in July, me and my roommate wired it on his computer, ran an ethernet cable through the walls of our closets, bought a second ethernet card to put in his computer.... and everything was gold. Ran the winxp networking wizard on his computer, it finished, then rebooted. Then ran the winxp networking wizard on my computer, it finished, then rebooted.
Have had internet on both computers just fine...
Until he reformatted yesterday.
Since his reformat, I have built a new computer. My mobo (Asus A7N8X Deluxe) came with 2 ethernet cards built onto it.
So anyways, after his reformat, he ran the winxp network wizard again. Appeared to work just the same.
Ran the wizard on my computer again. Looking like gold.
But now no internet on the client machine.
So we wired up my machine to be the host to see if that would work.
No good either way.
All that we did with the network wizard the very first time that we sucessfully networked the computers was to just click straight through it, and it worked perfectly fine. The wizard did every damn thing for us and no problems arose.
Now it's crap.
Back a couple years ago, I had to wire up me and my mom's computer to share a cable modem, and I also did that the 2-NIC way and vaguely remember setting IP addresses to 192.168.0.1 and such. But now I have forgotten.
If anybody has suggestions, instructions, such and such so on and so forth, I would really appreciate it. I will name my first born child after you if you can successfully point me in the right direction that will get this to work once more.
*side note*
I have read tutorials and such as to what IP addresses to assign to the outgoing NICs between the computers and that is fine and such, but the problem lies within my ISP I'm afraid. The picture below is what I must set for the NIC that is directly connected to the DSL modem. This is a big part of what is confusing me, as I have never had an ISP that didn't "assign automatically." My internet connection remains on with any number for the last number in the IP address field as long as it is between 2-255.

I don't do ICS myself... I have a Linux machine specfically set up as a NAT. However, some things that are clear in regards to your particular setup:
<li>Your DSL modem is already a NAT. the use of a 192.168.*.* address on your host machine proves that much, as that subnet is reserved for LANs. The modem takes it and translates it to your actual IP.
<li>It isn't the MACs.
Questions.
<li>Can each machine 'see' one another? As in, on the network neighborhood.
<li>Did the host set up ICS properly?
<li>Are either of you using an internal firewall? Including the WinXP mini-wall?
<li>Is the DHCP server started on the host machine, and the client set up to automatically retrieve?
<li>After the reformat, did he properly reinstall all the networking components he had before?
<li>Have you tried both network ports on the machine with two?
Should be able to give a hand one way or another as I'm a network technician. <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'><!--endemo-->
tale pretty much summed it up
If it is a MAC problem, some NICs allow you to change your MAC addy, so if you have the original you could use that.

Same way. Open a command prompt and type ipconfig /release then ipconfig /renew
*Edit*
And btw, if youre not using a router the gateway on the second machine (the one not connected, just sharing internet) should be set to the IP of the first computer. I think. PM monse he knows this stuff. I've probably sent him 20-30 PM's about computer junk <!--emo&:D--><img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'><!--endemo-->

I'm not really sure what your trying to say, but both of the ways I can interpret it are wrong.
Interpretation 1) The system acting as gateway should have the same IP as the other system.
Answer 1) Thats crazy talk, two systems having the same IP is bad voodoo.
Interpretation 2) The system acting as gateway should have the first IP in the subnet.
Answer 2) Not nessesarily, a DHCP server can have any IP it wants really.
Perhaps you meant to say that he should make sure that the non-gateway system is set to use the gateway system's IP as its gateway?

Uhm.. yes what you said... i think you just overcomplicated it because thats what I said... or what I think I said.
Questions.

<li>Did the host set up ICS properly?
<li>Are either of you using an internal firewall? Including the WinXP mini-wall?

1. no
2. All that I did was run the WinXP networking wizard. All of the NICs say "enabled, shared"
3. WinXP firewalls have been disabled.
4. eh...<!--emo&???--><img src='http://www.unknownworlds.com/forums/html/emoticons/confused.gif' border='0' style='vertical-align:middle' alt='confused.gif'><!--endemo-->
5. yes
6. yes
BTW, i have a linksys router that I used when I used to have cable modem. I tried that first with this, believe me. Everytime I got close to finishing with the router's configuration, it would tell me to enable DHCP and wouldn't go any farther. So I check, and lo and behold, DHCP is already enabled. So I go back to configuring the router, and it keeps telling me to enable DHCP. It won't go any further than that. Guess I'm stuck.
Open up the services manager (services.msc in your start --> run prompt)
Look for DHCP Server Service on the DHCP Server machine
Look for DHCP Client Service on the DHCP Client machine
It will ask you to conect your DSL/Cable modem to ONE computer (without the router in between) it will copy the settings, and then ask you to connect the router, once thats done it will apply the copied settings automatically.
