Windows 7: Unable to connect to one PC, but can the other way

Alright, well I've just gone down the homegroup method. Created one on PC-1 and connected to it with PC-2 with the allocated password - fine. The issue still lies in that I can't access the PC-1 from PC-2 through both the 'Network' section of Windows, or going to the user under the 'Homegroup' section...

In that case try running a system file scan on the PC with the problem.

Run the following command in an elevated command prompt. Let me know if it passes the scan or not.

Code:
sfc /scannow

Man we have really opened a can of worms on this one but I'm sure that I can't possible help with this problem because quite frankly none of it makes any sense at all. I'm pretty certain that if I could actually see this network the problem would be painfully obvious.

I know, it is extremely weird and a shame quite frankly. By saying you want to "see [the] network" do you mean physically? Or over TeamViewer or something?

Well basically if I was the guy setting it up physically, I would have found a way to run the Ethernet and take the ICS out of the equation and then check that IP's are in the same subnet. ICS is not good in the middle of a network.

Perhaps if you can post the ipconfig/all from each machine then it might tell me something.

The problem with ICS is that it sets up it's own little subnet that won't be in the same subnet as the router. That would explain some of the problems. Usually it's something in the 192.168.137.1 or something like that by default.

So setting up a static IP on the ICS machine in the same subnet as the router is using would fix that type of problem. Or configure the machine handing out the ICS to use IP's that are in the same subnet as the router.

In either case the use of ICS is inherently the cause of the problem as I first suspected.

I see what you mean. I'm going to research further into networking later on tonight, because I want to learn about all this subnet business, haha. Here are the three ipconfig /all returns.

PC-1 Private Paste - Pastie
PC-2 I run the line and it returned me with 348 "Tunnel adapter local Area Connection" lines, so I doubt this contains any crucial information: Private Paste - Pastie
LAPTOP Private Paste - Pastie

Ok wow, what a mess, it's no wonder the ipconfig is the first thing I want to see.

As I originally expected, ICS and it's byproducts are the cause of all problems, this is why I tell people to not use it without having to explain the entire reason why which is something most people won't understand...

First off there are two different subnets here starting with PC-1, the wireless is using 192.168.0.1 where the Ethernet is using 192.168.1.1 and for some reason the subnet ending in 1.1 is using a static IP? Is this the machine sharing the connection?

Second machine with all the tunnel adaptor problems which in itself can create the problem described. I'll assume this is the machine borrowing the connection "ICS" from the first machine? ...I have a special file to remove those tunnel adaptors which is a big problem.

The third PC is in the correct subnet ending in .0.1

You need to unzip and run the tunnel adaptor removal file on PC-2, after that reboot the machine and check the ipconfig/all to make sure they are removed except for just one which is normal. If they aren't all gone run the removal file again and reboot. If you can post the ipconfig/all again that would be helpful.

Hahaha, they do look pretty messy.

Er, no idea really. I followed a small YouTube tutorial earlier which told me to put these default gateways and IP adddresses in on both of the computers, so I did that...

Yes it is the machine "borrowing" the connection as you quite rightly said.

Yeah, I thought that one would be OK - I haven't touched anything on there, it's all nice and tidy.

I'm going to do that now and get back to you. Thank you very very much for your help so far. I'll go through and rep you after this (will [I have faith in you! ]) be fixed.

Ah, that looks much more tidier. Neat little tool that, thanks a lot.

I disabled my Wireless Connection on this PC because as you know, I'm using my internet through ICS. And here are the new results...
