Let us say that you checked your media state and your link light and you have physical network connectivity. To do this, open the Network and Sharing Center and assuming you have a connection, click on the View Status for your connected network interface. Figure 3: Viewing the Status of your Connection.
If you take a look at the details for the connection in Figure 4, notice that this connection has no default gateway or DNS servers. Lack of these will certainly prevent you from really using your network connection as normal.
Of course, neither of these are required but most of us want to communicate outside of our local LAN. A default gateway is required for that. Also, most of us want to communicate with servers by name such as using www. Even if you do have a valid IP address, default gateway, and DNS Servers, you should ping these to ensure that you can really communicate with them. Fortunately for those who do not want to get into troubleshooting, Vista does offer the automatic Diagnose and Repair of network connections.
To use diagnose and repair, just open the Network and Sharing Center and click on Diagnose and Repair. Figure 6: Diagnose and Repair.
This tool will go through and check your network connection to identify problems. It will tell you basically what is wrong in the network connection but if you want more detailed information, you can check the Event Viewer. Firewalls are used to filter inbound and outbound network connections. Of course if the firewall is out on our LAN that is beyond the scope of this article.
As for firewalls on your local Vista computer, you can even have more than one but the first one if you installed a 3rd party firewall.
To test whether performance issues are related to Aero Glass, disable Aero Glass on the computer. To do this, follow these steps:. In Windows Vista, right-click the desktop, and then click Personalize. When Aero Glass is disabled, try to reproduce the performance issue to see whether the problem still occurs.
If you no longer experience performance problems, the hardware may be unable to use Aero Glass to produce an optimal visual experience with Windows Vista.
If you want to use Aero Glass and to avoid an adverse effect on performance, you must upgrade your hardware. In this case, you most likely have to upgrade the computer's video card. If you decide to upgrade the video card, make sure that the card that you selected has the "Certified for Windows Vista" logo.
To view this logo, visit the following Microsoft Web site:. In this case, you must re-enable Aero Glass before you continue to troubleshoot the performance problem. You may have to contact your computer manufacturer or hardware vendor to determine whether your computer supports Windows Vista, or whether there are any updates that must be installed to make the computer compatible.
When you start the computer in safe made, you can determine whether the cause of the startup-related performance issue is related to a background service or to a driver. To start in safe mode, follow these steps:. Click Start , click the arrow next to the Lock button, and then click Restart.
Press and hold the F8 key as your computer restarts. Note You have to press F8 before the Windows logo appears. If the Windows logo appears, you must try to restart your computer.
To do this, wait until the Windows logon prompt appears, and then shut down and restart your computer. If the problem continues after you start the computer in safe mode, the problem may occur for one or more of the following reasons:. If you can verify that the problem continues to occur when you start the computer in safe mode, restart the computer in normal mode, and go to the next troubleshooting step. If you verify that the performance issue does not occur in safe mode, start Windows Vista in a clean-boot environment to determine the programs or the services that are causing the issue.
This process will systematically eliminate any of the third-party services or applications that are running on the system that could potentially be the cause of the problem.

No jargon. Pictures helped. I'm currently wondering if your router, firewall or some other security software is blocking ports that must be open to communicate with the backend GFWL servers. You might want to try temporarily disabling your firewall to see if that allows a connection to the GFWL server. If there are no connection problems when you boot up into Win 7 SP1, are some of the games you want to play not compatible with Vista SP2, or are you just curious why you're having connection problems since reinstalling your Vista SP2 OS?
I don't know why, but Microsoft made changes to the metadata of multiple Vista SP2 security updates in their Microsoft Update Catalog around March that likely affected the Vista SP2 updates posted on their Windows Update servers as well hence the new requirement to apply the MicrosoftRootCertificateAuthority I'm still waiting to hear if using Firefox ESR v For example, I still don't know what antivirus, if any, you use on your Vista SP2 machine, and I know of several users who had to add exclusions for the Steam executables in their antivirus software before they could run Steam on their system.
Did you follow the instructions in the Steam support article Troubleshooting Network Connectivity to try to diagnose your connection problem? If you applied the MicrosoftRootCertificateAuthority Good day i have windows vista on one of my retro machines for gaming etc. This thread is locked.

One particular problem involves connectivity problems between Vista and previous Windows versions mostly XP when they are on the same network. You might be able to connect to another computer just fine, but as soon as you try to copy a file, you run into trouble. You typically receive an error message that you don't have permission to copy the file. Microsoft has acknowledged see Microsoft Knowledge Base Article that Windows Vista may not function correctly with "outdated routers".
Microsoft has released an Internet Connectivity Evaluation tool to test your router's compatibility. The very first thing you should do when having connection problems with Vista on your network is to check for updated drivers for your network card on the manufacturer's Web site. Also check for the latest firmware version of your router. If you run the Internet Connectivity Evaluation tool, and it shows that your router does not support "TCP Extensions for High Performance", you can either change your router, or switch off the feature in Vista.
To do this, you'll have to open an elevated command prompt:. Click Vista's Start button, and in the Start Search box type cmd. At the top of the Start menu under the Programs header , you will see cmd.
You should get a response Ok. To check, you can run the command netsh interface tcp show global. One of the symptoms you can use to identify the failure of receiving an IP address from a DHCP server is that your computer's IP address will be listed in the It may not be true in all cases that the failure to obtain a correct IP address is caused by the incompatibility of your DHCP server, but it's another thing to troubleshoot. Microsoft issued a fix for this issue back in September See Microsoft Knowledge Base Article There have been several problems identified, and Microsoft has issued fixes for these back in September as indicated in Microsoft Knowledge Base Article :.
The hotfix for these issues is not yet publicly available.
