Windows 7 name resolution problem

Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. My best guess to explain what has happened is the result of your using the latest driver.

It is not uncommon that those drivers to cause this problem. That is why I am suggesting you try to use the older driver that you replaced instead.

This will usually cause a delay of just a few seconds. File Name: Tcpipimp2. Windows More Need more help? Expand your skills. Get new features first. A subscription to make the most of your time.

Can you help us improve? Computers use numeric IP addresses such as However, IP addresses are difficult for people to remember, so we use more friendly host names such as www. Name resolution is the process of converting a host name to an IP address, and DNS is by far the most common name resolution technique.

Many apparent connectivity problems are actually name resolution problems. If any of the following problems occur, the client will be unable to contact a server using its host name:. If any of the following problems occur, the client will be unable to contact a server using its host name: DNS servers have failed.

The network connecting the client to the DNS server has failed. If necessary, update the client computer's DNS server configuration. Contact the server or network administrator for additional assistance. If Nslookup displays the message "Default servers are not available," the computer does not have a DNS server configured. Update the client network configuration with DNS server IP addresses or configure the computer to acquire an address automatically.

If the IP addresses are different, consider changing the problematic client computer to use those IP addresses. Instead, you can install and use the PortQry tool. You can use the Hosts file as another name resolution method. You might do this if you know that your DNS server is unavailable or the database is out of date, you need to access a server, and you know the server's IP address. It's also useful when you've recently installed a new server and you want to contact it using a host name before the DNS database is updated.

Although you can typically contact servers using their IP addresses, Web sites often need to be reached using the correct host name, and IP addresses might not work. It is a text file, and you can edit it using Notepad.

To open the Hosts file, run Notepad using administrative permissions. To add an entry to the Hosts file to enable name resolution without using DNS, add lines to the bottom of the Hosts file, as demonstrated here for IPv4 and IPv6 addresses. After updating the Hosts file, you can contact servers by using the host name.

In fact, the only application that bypasses the Hosts file is Nslookup, which always contacts DNS servers directly. Remember to remove entries from the Hosts file after you finish using them; otherwise, you might have name resolution problems later if the server's IP address changes. Often, network problems don't result in total loss of connectivity. Network problems also can be file transfers that take longer than they should for your network bandwidth, jumpy streaming audio and video, or extremely unresponsive network applications.

To troubleshoot network performance problems, you must first identify the source of the problem. Several different components can cause performance problems:. The local computer Your local computer might have an application that is using all of the processor's time, thus slowing down everything on your computer, including networking. Alternatively, failing hardware or problematic drivers can cause performance problems or intermittent failures.

To solve these problems, you can stop or reduce the impact of problematic applications, replace hardware, or upgrade drivers.

The network infrastructure Overutilized routers cause increased latency and dropped packets, both of which can cause performance problems and intermittent failures. Routing problems, such as routing loops, can cause traffic to be routed through an unnecessarily long path, increasing network latency.

Sometimes, such as when you are using a satellite link, latency and the performance problems caused by latency are unavoidable. The server If the server is overutilized, all network communication to that server will suffer performance problems. To identify the source of a network performance problem, follow these steps.

After each step, test your network performance to determine whether the problem still exists.
