Windows 7: Internet Connection Sharing - Enable

29 May 2011   #20

Windows 7 Ultimate x64

Hi severdsolo! (good morning?)

Here are the results of the ipconfig /all command in the XP machine.

You'll see that I've tried to cofigure the Default Gateway (I think "Puerta de enlace predeterminada" stands for "Default Gateway") pointing to the Win 7 Machine... well I must say that it is not currently working. At least my (XP) Firefox web browser seems not to be able to "solve" the address ""

Ok, I'm not seeing any DNS server's there.

Firstly, please make sure any Firewalls (excluding the default Windows one) are disabled. You can always put them back when this is working, but for now, let's not confuse the issue. I would recommend temporarily uninstalling all 3rd party firewalls, as sometimes merely disabling it isn't enough.

Next, The big problem that I can see there is that the XP machine has no DNS servers.
Try typing into your web browser. If you get google come up, then it's a DNS problem. In which case, move on to the next step:

GO to your network adapters screen (sorry can't remember where it is in XP... it's the same screen where you set up the static IP and default gateway though)
Right click "Marvell Yukon 88E8072" and then click Properties.
Highlight Ipv4 then click Properties.
At the bottom, unselect "obtain DNS server addresses automatically" and instead select "use the following DNS server addresses"
Make the primary leave the secondary blank

See if that works, if not try setting it to the same as your WIn 7 machine:

Well, I've disabled my Norton Firewall on the XP system and even the Window's Firewalls on the Win 7 (now restored to its operating state).

I've typed the and waited... Now I get a slightly different message: "The server is taking too long in responding" (my translation).

I suppose we have failed to skip the first obstacle...

I think I begin to understand your steps... What would you recommend next?

try opening a command prompt from the XP machine, and ping I'm just curious about whether or not it's actually getting through.

I would highly recommend you completely uninstall Norton, it's been known to play havoc with this sort of thing: Download and run the Norton Removal Tool to uninstall your Norton product | Norton Support

As I said, you can always put it back later.

Out of interest, what happens if you set the DNS as I outlined anyway? Is there any improvement?

At bottom is the result of the ping thing (seems not being working):

I've followed the steps of the other suggestion: no improvement in neither case (neither accessing via nor via "" and with both sets of DNS IP's).

Now proceeding to uninstall Norton's. I'll tell you the result.

Windows 7 Professional 32-Bit

Hoping someone here can help me, I've confused myself into a right mess.

Here's the situation - modem and router downstairs, along with a PC. 2nd PC upstairs, alongside Bluray player.

1st PC is connected to the router via Ethernet, 2nd PC by WiFi. Hoping to share this connection over an ethernet cable to the bluray player.

Whenever I try to enable haring I get this message:

"Internet Connection Sharing cannot be enabled. A LAN connection is already configured with the IP address that is required for automatic IP addressing."

I get this error regardless of whether I have everything set up with static IPs or auto IPs.

Could someone give me settings that they think should work? At the moment the router is on and using DHCP to assign IPs on the network. There are numerous other devices that connect to this, including a PS3, 2 android phones, iPods, iPads and a couple of laptops (but not all at once).

I also have a spare wireless router lying around (Netgear - the router in use is a Belkin). is there anyway I could use this to help my situation?

Hi Severedsolo!.

Sorry that I have been so silent. My new computer suffered a crash in the audio card and It's been out this last two weeks.

I've now the computer again and I honor here the social duty to inform you of the apparent ending of the story.

I make a list of the thigns I've done to achieve our goal. Nevertheless I can't say which of them actually solved the problem.
  1. I changed from Windows 7 Ultimate to Windows 7 Professional.
  2. I checked that stopping the windows firewall in the Win 7 machine (very, very important step I think) I gained PING access from de XP machine to the W7 machine.
  3. As I am not enough skilled with the Windows firewall I decided to install the Norton one in the Win 7 Machine.
  4. I activate the (Windows) facility "Allow users of other networks to access Internet through this machine" in the Sharing tab of the Intenet connection of the Win 7 machine. (Of course it threatens me with changing the static IPs to automatic ones but I'm too tired to think about the meaning of it).
  5. And it works! Now I can access the internet from any machine of my local area (ethernet) network regardless of the operating system in them.
Well, I hope it's really finished. Thak you very much for your advices and patience. If you can diagnose which of the medicines were really useful, perhaps other users will appreciate it.
