There are a variety of reasons these types of DNS errors can occur. Fortunately, most of them have simple resolutions. In fact, fixing the issue could be as easy as restarting your computer or changing web browsers.
Either of these solutions will automatically recognize your system and locate the appropriate drivers for you to use with it. We recommend this method because it eliminates the risk of human error, such as downloading or installing the wrong driver on your device.

Whenever you type a URL into a Web browser, your PC asks your domain name service server (DNS server) to translate that URL into an IP address, and caches that information. That cache can occasionally become outdated or corrupt, which can cause Internet connection problems. To clear your DNS cache, open the Command Prompt with Run as Administrator, type ipconfig /flushdns, and press Enter.
Suddenly you cannot access any websites through the Internet. Then you try to troubleshoot the network problems on your Windows. It tells you the DNS server not responding is the culprit. You may see one of these:
For example, when you want to access our website: www.drivereasy.com on Chrome, the DNS server translates it into our public IP address: 144.217.68.24 for Chrome to connect to.
So if nslookup can translate, then lots of things work: networking hardware, NIC adapter driver, internet connectivity to the DNS servers, and successfully accessing the servers to do a translation. That's a lot!
The problem happens when the DNS server is set to the university's; or when set to google's 8.8.8.8 and/or 8.8.4.4 and/or OpenDNS's 208.67.222.222 and/or 208.67.220.220. Which makes sense given that Wireshark reports that Windows isn't even sending the name query.
This is quite an interesting result. What this means is that the Windows DNS Client looks for either Domain or 2 or all 3 of these "values" in the registry. And if it finds it (them), it's fine. If it doesn't find them, specifically if it does not find the Domain, it errors out and simply fails. No error report [1].
There might have been an error report, but not in the Event Viewer in the common places (under the hierarchy: Event Viewer (Local) -> Windows -> Application, and System). There are other logs, many not turned on by default, that might have had some output, especially
Helpful hint if this does not solve your problem: When searching the internet for Windows DNS problems, be aware that a lot of posts are talking about a Windows server functioning as a DNS server. Our issue was that we had a plain old PC connected via a router to the internet and our DNS client software was not working. Sometimes reading posts I missed that distinction.
Reinstall TCP/IP (please continue reading...). I don't mean "reset it", "restart it", "re-enable it".In Windows 10 run "netcfg -u ms_tcp". This will IN FACT remove the protocol from your system. No more TCP/IP v4 on it.Reinstall the protocol the usual way (properties of network connection; add protocol).In windows 7 you could edit nettcpip.inf to allow you to unistall the protocol from the network connection properties, but that is not possible in Windows 10 (can't say in 8 nor 8.1).Hope this helps someone.

The root of such irritating messages can often be traced back to the server outage. In such cases, the DNS server is temporarily unavailable. Most of the time, these problems can be corrected by changing browsers, or switching a few of your firewall settings. Restarting the router or changing the DNS server can also solve the problem.
Using a public DNS server is also anoption; just look on specific DNS server lists. Google operates a fast, free, and very reliable public DNS server. How to set up these DNS servers via the router settings or under Windows 10 and Windows 11 is explained in the step-by-step instructions below.
If Internet Protocol Version 6 (IPv6) is used instead of the Internet Protocol Version 4 (IPv4), then the IPv6 addresses of the DNS server must also be exchanged. The public DNSv6 addresses of the Google servers are:
If Internet Protocol version 4 (IPv4) is used instead of Internet Protocol version 6 (IPv6), select version 6 in the third step and set the corresponding IPv6 addresses. For example, for Google servers, these would be 2001:4860:4860::8888 and 2001:4860:4860::8844.
You can also use Windows PowerShell to change the DNS server. This method is more suitable for experienced users. With just a single command, you can change the DNS server without having to click through all the Windows menus if, for example, the currently entered DNS server is not responding.
You can find out whether changing DNS server has solved the problem by carrying out a simple test. Enter the URL of a well-known site in your browser e.g. If the site can be accessed, it means the DNS server is functioning properly.
The duel between Linux and Windows may have an obvious victor on the home computer front, but the battle for server use paints a very different picture: since the beginning, Linux has bested Windows, as usage figures show. But many users remain unconvinced by statistics and rightfully ask the question: what are the actual differences between the two platforms?
This article is intended for technical support agents and IT professionals. If you're looking for more information about Windows activation error messages, see Get help with Windows activation errors.
This article provides troubleshooting information to help you respond to error messages that you may receive when you try to use a Multiple Activation Key (MAK) or the Key Management Service (KMS) to perform Volume Activation on one or more Windows-based computers. Look for the error code in the following table, and then select the link to see more information about that error code and how to resolve it.
The error text is correct, but is ambiguous. This error indicates that the computer is missing a Windows marker in its BIOS that identifies it as an OEM system that is running a qualifying edition of Windows. This information is required for KMS client activation. The more specific meaning of this code is "Error: Invalid Volume License Key"
This error occurs if the KMS client contacted a KMS host that could not activate the client software. This can be common in mixed environments that contain application-specific and operating system-specific KMS hosts, for example.
This article describes several common error messages that can occur when you join client computers that are running Windows to a domain. This article also provides troubleshooting suggestions for these errors.
Additionally, verify that the computer can reach a DNS server that hosts the DNS zone of the target domain or can resolve DNS names in that domain. Make sure that the correct DNS server is configured on this client as the preferred DNS, and that the client has connectivity to that server. To verify this, you can run one of the following commands:
An attempt to resolve the DNS name of a domain controller in the domain being joined has failed. Please verify this client is configured to reach a DNS server that can resolve DNS names in the target Domain.
Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
Verify that the computer can reach a DNS server that hosts the DNS zone of the target domain or can resolve DNS names in that domain. Make sure that the correct DNS server has been configured on this client as the preferred DNS, and that the client has connectivity to that server. To verify this, you can run one of the following commands:
The error may be transient. Try again later. If the issue persists, verify the status of the DC that the client is connecting to (active connections, network connectivity, and so on). You may want to restart the DC if the issue persists.
This error occurs when you use the domain join UI to join a Windows 7 or Windows Server 2008 R2 workgroup computer to an Active Directory domain by specifying the target DNS domain. To fix this error, see 2018583 Windows 7 or Windows Server 2008 R2 domain join displays error "Changing the Primary Domain DNS name of this computer to "" failed....".
Check that the domain controllers (DCs) are registered by using correct IP addresses on the DNS server, and that their Service Principal Names (SPNs) are registered correctly in their Active Directory accounts.
This error is likely a transient error that is logged when a domain join searches the target domain to determine whether a matching computer account was already created or whether the join operation has to dynamically create a computer account on the target domain.
This error can occur when the Kerberos token size is larger than the maximum default size. If this situation, you have to increase the Kerberos token size of the computer that you try to join to the domain. For more information, see the following Knowledge Base articles:935744 "Not enough storage is available to complete this operation" error message when you use a domain controller to join a computer to a domain327825 Problems with Kerberos authentication when a user belongs to many groups 2ff7e9595c
