I'm not using homegroups for sharing. ICS is indeed already on, I tried a network bridge but it didn't go so well, maybe because I'm not that experienced in setting that up.

I'm not using a router because as of last week everything was working without a problem so I know that my setup works without needing to buy a router if I have two nics why not use them right?

PC2 NIC ( IP = 192.168.1.8, subnet=255.255.255.0, Gateway = 192.168.1.1)

See if you can now ping PC1 to PC2
PC2 will not get Internet connectivity without a software network bridge.

It looks like the connection is shared so that might be done already. You might try a network bridge also. Although I'm not sure why you wouldn't just use a regular old router for all this?

You might want to check in the Advance Sharing settings to make sure everything is like the picture below. Sometimes they change by themselves apparently.
A regular router would be easier, but lets entertain his request.

Your setup will work. This is what needs to happen though.

The PC1 to router network segment is likely 192.168.0.x.

ICS will assign a separate network segment for PC1's second NIC and PC2, likely 192.168.1.x.


Normally, ICS will prevent file sharing between PC1 and PC2 because they are on different network segments. That's the normal behavior. So what you are seeing right now is normal.


To restore file sharing and still keep internet connectivity on both machines, you'll have to use a software network bridge.

That is a multi step process.
  1. Turn off ICS
  2. Go to advanced adapter settings under Network Sharing Center on PC1
  3. Select advanced adapter settings
  4. Select NIC 1 and NIC 2 and right click one of them
  5. Select "bridge network connections"
  6. Make sure both PCs are on "automatically obtain IP settings"

What is going to happen is that PC1 and PC2 will be on the same network segment and thus be able to share files now. And PC1 will forward internet connectivity to PC2. Try this.

You may run into problems where PC2 will not be able to get a IP address. You'll know because if you IPCONFIG on PC2, you'll get a 169.x.x.x. In that case what is happening is that PC1 isn't forwarding the DHCP requests and acknowledgements, which sometimes happens because Windows is retarded. In that case, you need to assign static IP addresses. If your router is 192.168.0.1 (make sure by pinging it), then assign PC1 (192.168.0.2) and PC2 (192.168.0.3). The subnet mask will be the same on both (255.255.255.9) along with the gateway and DNS settings (192.168.0.1).

Hope that helps.

I mentioned using a network bridge earlier but the Op thinks if ICS worked before it should work again which makes at least some sense.

Hey guys, thanks for the help.

I figured this was taking too much time and was frustrating me so I decided to format my windows partition and now everything is working like it used to. I have my two nics auto configured and network and internet sharing and everything is running perfect (except for homegroups which I never used so...), so no router needed like I said.

I think I can format and get all my progs back running in less time than it would take for me to get this to work with configs so I'm happy to fix it this way .

Again thanks for the help.

Cheers

That is the good thing about Win7 is you can reinstall it in a matter of minutes. Sometimes that is the easy way to fix things.

Oh yes, I've figured that out myself. And with sites like ninite I can just create a setup with all my common progs and install them in minutes. Then I hop on opera and load my settings and I'm good to go. The only thing that takes a bit more time is reinstalling my games but It's all good.

Yup the games take awhile to reinstall but it's easier than tracking down some obscure problem that you could spend hours trying to fix. Glad you got it working.

Thanks.

Obscure is the right word, having stuff suddenly stop working for no apparent reason...bah

Odd that a reformat solved the problem. I predict he'll be back.
