Hi, I don't know if this is been asked before as specifically as this, perhaps someone could link me if it has or help answer my problem. I am an "experienced" computer user, in the sense I'm good with OS, I'm good with games, and I am an intermediate level programmer (says my IT grades) and I also do a bit of web development. However I'm new to networking, and I am attempting to network my two pcs. My pc specs are as follows; Windows 7 Ultimate 64bit 4GB RAM, AMD Athlon X2 245 Processor 2.9ghz And the windows experience rating is 5.9 My second pc is as follows; Windows 7 Professional 32bit 1GB RAM, AMD Sempron Processor 2800+ 1.6ghz And the windows experience rating is 2.5 I am attempting to network the computers with two standard ethernet cables and a 10/100mbps ethernet switch (TP-LINK TL-SF1005D 5 port). I've managed to get everything working, IPv6, 6to4, and some other stuff... but I can't get this IP configuration problem out of the way. This problem is stopping me networking my two pcs fully... the only thing I can get through it is file transfer. I want to network my pcs for a few reasons, including multiplayer LAN gaming, network programming, and an internal server setup for testing site developments in progress. Does anyone have any ideas how I could fix this? (It has nothing to do with the "Bonjour" service i've read about... I looked, no success) I don't plan to share internet between the pcs, rather have a minimal internet solo to the pcs hosted by me (for web development testing purposes as mentioned above). I don't run any modems, just a mobile internet dongle via vodafone.

start by posting the result of ipconfig /all for all systems

These are the results for my pcs in order of the pcs as listed above. ----- PC1 ----- Windows IP Configuration Host Name . . . . . . . . . . . . : PC1 Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No PPP adapter Vodafone Mobile Connect Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Vodafone Mobile Connect Physical Address . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : Im.Smart.With.Security Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 0.0.0.0 DNS Servers . . . . . . . . . . . : 10.206.65.68 Primary WINS Server . . . . . . . : 10.11.12.13 Secondary WINS Server . . . . . . : 10.11.12.14 NetBIOS over Tcpip. . . . . . . . : Disabled Ethernet adapter Bluetooth Network Connection: Media State . . . . . . . . . . . : Media disconnected Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Bluetooth Device <Personal Area Network> Physical Address. . . . . . . . . : 00-0A-3A-81-51-4F DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : NVIDIA nForce Networking Controller Physical Address. . . . . . . . . : 00-24-1D-67-28-C1 DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Autoconfiguration IPv4 Address. . : 169.254.22.95<Preferred> Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : NetBIOS over Tcpip. . . . . . . . : Disabled ----- PC2 ----- Windows IP Configuration Host Name . . . . . . . . . . . . : PC2 Primary Dns Suffix . . . . . . . : Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : SiS 900-Based PCI Fast Ethernet Adapter Physical Address. . . . . . . . . : 00-01-6C-F9-C6-0C DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Autoconfiguration IPv4 Address. . : 169.254.100.58<Preferred> Subnet Mask . . . . . . . . . . . : 255.255.0.0 Default Gateway . . . . . . . . . : NetBIOS over Tcpip. . . . . . . . : Disabled

well you do not have valid IPs on the PC's 169.254.xxx.xxx are auto assigned by windows.You need to assign each pc a IP address.this is not really a win 7 question but a networking 101 questionyou need to google "how to network two computers"

My head hurts from doing so much googling, I came here as a last resort from being unable to find a google result that I could actually understand, I found one but it described a process which I have no idea how to do on windows 7, thats the whole reason I posted into windows 7 networking... because I'm using windows 7 and i've never networked before, on any os. Could someone please just give me step by step instructions of exactly how to assign IP addresses to my pcs, or atleast link me to something that I can atleast relate with windows 7? I don't mean to be snappy I'm just so sick of being unable to do something that so many people claim to be simple, for 2 weeks now... Thanks for recommending an already tried method of figuring out my problem!

If your machines are getting 169.254 IP addresses, it means that they are configured to get an IP address automatically but no DHCP server is available to supply that address. In this situation they will configure an APIPA address in the 169.254.0.0 subnet. What exactly are you trying to do? If all you need is communication between these two machines, APIPA addresses are adequate. APIPA addresses only fail if you need to connect to machines outside the local network. If you want the second PC to share the other PC's Internet connection you will need to install ICS (or third party NAT software). The first machine will get a static IP when you install ICS. The second PC will then get its IP config from DHCP in ICS/NAT. Read the help file on ICS in Windows 7 help.Bill

Here is the problem - Autoconfiguration IPv4 Address... Assign a private ip to each pc...e.g. 192.168.1.51 So make the other one... 192.168.1.52 the subnet should be 255.255.255.0 To do this...open control panel>network and sharing center click change adapter settings right click properties on local area connection go to properties of tcp/ip v4

Ok I have no idea what you're on about, I think I get the general idea though. The problem is my LAN isn't allowing anything but file transfer between the computers. I cant even create a homegroup, and join the computers to it. And it all boils down to the problem with the IP config being invalid, and that boils to what the guy above said I do believe, assigning the ips manually. I mentioned what I wanted to do exactly in more detail in my first post at the bottom. So I really don't think APIPA ips will suffice for my network, just what my pc keeps saying when I try to do stuff.

Ok I think you have me a step further, not sure yet. I still can't create a homegroup; it throws this at me, "Your network connection must have IPv6 enabled to create or join a homegroup. To enable IPv6, start the HomeGroup troubleshooter." And I feel it hit my head >.< ok I thought that I previously enabled IPv6 but something is stopping it. I have no idea whats causing this, and when I run the troubleshooter it says its unable to identify the problem. Ghasp...

It is your lack of network understanding that is the issue.I suggested you do some reading in hopes you could learn just a little a bit.Had you done as I said and goolged "how to network two computers" the second link provides everything you need to get your two computers talking.You need to forget about homegroup.You need just a simple little setup as has been posted here by crontab, but without some understanding of what you are doing and how to trouble shoot ityou would just be back here with more questions.Forget wizards and trouble shooters they can not help as they are ASSUMING your have a router / gateway (which by the way would make this easy).As you stated you are a gamer with the setup you are doing you are going to want to know / understand "the metric setting" so read on.

On the contrary, I DID do as you recommended, and googled "how to network two computers" I looked through every link, the first, the second, the third and so on. I did see the second with with the 4 steps how to, that was the one I refered to not being able to understand how to do it on windows 7 (step 3). Crontabs instructions helped me accomplish that. And I was told I would be able to setup homegroup with this network config, thats why I was wondering whats wrong with IPv6. I've not only googled how to network my pcs like you suggested, I also googled IPv6, and researched things like the "Teredo Tunneling Pseudo-Interface" and I believe the reason for my problem is that in device manager, this is infact conflicted (yellow exclamation mark). So now tell me that this is NOT a windows 7 networking issue! I was not introduced to computers yesterday, or 2 weeks ago, I am well aware of how to troubleshoot things. EVEN if I have very little knowledge of the things I troubleshoot. I am unable to update the driver for teredo, it says I have the latest version, I cannot rollback because this is a clean installation of windows 7 ultimate, and I've tried reinstalling the driver and to no success. And its the same on my second pc too, they both say the same thing, "This device cannot start. (Code 10)". I've even tried disabling and re enabling the driver, no success. Now perhaps I don't need teredo, but if that was the case, why is it when I try to run games, and other network applications on my LAN, they fail. Yet these apps and games are known to work! Please I am not that dumb, so please can someone help me fix this?

No one is calling you dumb, you did fail to mention a few things but that does not matter.Teredo Tunneling Pseudo-Interface has to do with IP6 you can just disable it in device manager as you will not be using IP6.You setup is going to be "funky" with that Inet access and LAN being two networks.And no it is not a win 7 issue it is an IP6 issue, in your case nothing what so ever to worry with.The gaming issue I would guess is because of your setup, did you figure out the metric / route settings you need.None of this is win 7 related it is all networking 101.And with the questions you asked we can only assume you lack the basic networking skills, your post did not say you had any nor have you shown us other wise.once more not saying you are dumb, just saying you need to know more about networking to understand what it is you want to do.Now if you did not wish to learn, you just hire someone to come do it for you.

Hi, I think you can try ICS. For more information, please refer to: Using ICS (Internet Connection Sharing) Hope this helps. Thanks. Nicholas Li - MSFT

I had networking problems as well. 3 computers running Windows 7. 2 had Adobe CS3 installed which brings with is a piece of software called Bonjour. These two computers had no end of networking problems. 1 was a desktop connected to the router and the other was a laptop connecting via WiFi. Third computer didn't have CS3 and didn't have any trouble at all. In trying to find a solution (nothing seemed to work), I came across the solution shown below in a different thread and thought I would share it. I installed the upgrade for Bonjour (it's listed as Windows Vista 64 software) and all of my network problems cleared up. My thanks to "PDX Prod Mgr". Brilliant! " PDX Prod Mgr I had the same problem when I rebuilt my Windows 7 system. I had CS3 installed on my system, it installs an old version of bonjour. If you inspect your program files\bonjour directory, see if you have an EXE and DLL file dated 2006. Jump over to apple's website and search for windows bonjour. I found the newer download here: http://support.apple.com/downloads/Bonjour_for_Windows Download and install this (you don't have to uninstall the old Bonjour) and reboot. This fixed my install and I no longer have the network error you describe. If you look at that folder now, you will have the newer DLLs (and some other gunk.) "

Hi guys! I have had the same problem for a few days now, and have searched numerous forums and gone through hell and high water to fix it. nothing helped until I found the ultimate solution that will help everyone: CALL YOUR ISP, TELL THEM WHAT HAPPENED AND THEY CAN CONFIGURE A NEW IP ADDRESS FOR YOUR CONNECTION. IT ONLY TAKES ABOUT HALF AN HOUR. During this time you must keep your router/modem turned off, and after the ISP has fixed the problem (in my case it took half an hour) you must restart your machine with the router/modem on and connected. From then on it should be like nothing ever happened. Just for the fun of it, here's a list of things I have tried without results: release/renew ipconfig restarting modem/router and computer about a zillion times changing LAN card creating a static IP resetting winsock in command prompt reinstalling Windows 7 reinstalling XP (I had a dual boot and I did both, losing all installations) manually entering IP address disabling/enabling local area connection plugging and unplugging LAN cable uninstalling and reinstalling LAN card driver resetting modem/router using the reset button And after all this, all it took was just a phone call. This is because your ISP is THE ONLY authority when it comes to configuring your IP address. In this case, it can only be done from the outside. this is also the reason why Microsoft didn't announce any patches or fixes for this problem, because it is not their problem and responsibility. Only one question remains, WHY is this happening? Noone has been able to answer this, and I have read tons of forum posts about it. Maybe even the guys that made Windows 7 don't know it. I am going to copy this post on several other forums because I have seen the trouble that people are having with this problem. If you find out why this is happening, please post it here.
