Key notes

In the TCP/IP protocol suite, the Domain Name System is one of the protocols that provide computer name-to-IP address mapping name resolution services. However, sometimes it glitches resulting in errors such asThe requested control is not valid for this serviceNET HELPMSG 2191.The DNS Client and Server work together to provide computer name-to-IP address mapping name resolution services to computers and users.

Upon the Windows installation, the Client service is enabled by default in both client and server versions of the operating system.As soon as you specify the IP address of a server in your TCP/IP network configuration, the DNS Client queries the server to discover domain controllers as well as resolve computer names to IP addresses.It is only after the server responds to the client’s query and provides the domain controller’s IP address that communication can take place between the client and the domain controller and the authentication process can begin.

How can I enable DNS on Windows 11?

Some of the best third-party DNS servers to use are theGoogle Public DNS(8.8.8.8 and 8.8.4.4), Cloudflare (1.1.1.1 and 1.0.0.1), and OpenDNS (208.67.222.123 and 208.67.220.123). Each of these service providers has a primary and secondary DNS address that you can use to connect to.

Because it is so easy to remember, Google’s Public DNS is one of the most widely used addresses on the Internet.The fact that Google keeps a log of the IP addresses that access its servers for one to two days is important because it can be used for diagnostics and troubleshooting purposes.There may also be some long-lasting logs, but Google claims that it does not store any personally identifiable information in its logs. As a result,if you value your privacy, you may want to consider using a different DNS address.

What can I do if I get the NET HELPMSG 2191 error?

1. Restart DNS

You can create long-running executable applications that run in their own sessions using Microsoft Services, formerly known as NT services, which are available on the Windows platform.These services can be started automatically when the computer starts up, they can be paused and restarted, and they do not display any graphical user interface.It is important to note that because clearing the DNS cache removes all of the entries, it also deletes any invalid records, which forces your computer to repopulate those addresses the next time you attempt to access those websites.These new addresses are derived from the DNS server that has been configured for your network.

2. Use Registry Editor

In the Registry Editor, users can perform the following operations: creating, manipulating, deleting, and renaming keys and subkeys in the registry as well as modifying and deleting value data.However, if you are still unable to complete the above solution or it doesn’t work for you, check outwhat to do if you can’t restart the DNS client.

Why should I use third-party DNS servers?

DNS servers are responsible for connecting domain names to their associated IP addresses. The first time you enter a domain name into your browser, your computer contacts the DNS server that is currently in use and inquires as to which IP address is associated with the domain name.The IP address is then connected to your computer, which then retrieves the appropriate web page for you. Your Internet service provider is most likely responsible for providing the servers you use (ISP).If you’re behind a router, your computer may be using the router as its DNS server, but the router is actually forwarding requests to the servers provided by your Internet service provider.

Computers store DNS responses locally, which means that the request does not have to be made every time you connect to a domain name that you have already been to once or more times.Once your computer hasdetermined the IP addressassociated with a domain name, it will retain that information for a period of time, allowing you to connect faster by skipping the request phase altogether.

As we’ve established above, you’re most likelyusing the servers provided by your Internet service provider. However, you are not required to do so. Instead, you can make use of ones that are operated by a third-party company.

In some cases, these DNS servers may be able to provide you with faster resolves, allowing you to connect to a domain name more quickly the first time you connect to it.But, in practice, the actualspeed differences you experiencewill be determined by your distance from the third-party servers as well as the speed of your Internet service provider (ISPDNS)’s servers.
