But why does the error appear when connecting to the DHCP server in Windows? There are different causes and one of them is when we establish a connection for the first time after restarting the computer or if we have forced an IP renewal ourselves through the following commands:
- ipconfig /release
- ipconfig /renew
It could also happen after updating the system, that there is a program that is blocking the connection or a bad configuration that we have made. However, whatever the problem, you can usually fix it easily and you only have to follow a few steps.
Steps to fix this error
Let’s explain how fix error with DHCP server. You can carry out these steps in both Windows 10 and Windows 11. However, some possible causes may be more present in the latest version of the Microsoft system, such as a problem with the drivers of the network card. This can happen if you have updated the OS, but the drivers for the card are old.
The first and easiest thing you can keep in mind is to try the windows troubleshooter. We must try this whenever you come across a failure of this type. In the case of Windows 10 you have to go to Start, enter Settings, go to Update and security and once there click on Troubleshoot. You will have to mark Network adapter and continue the process until the end.
On Windows 11 you will also have this possible solution. In this case you have to go to Start, enter Settings, go to System and there click on Troubleshoot. Go to Other Troubleshooters and select Network Adapter and run it.
Once the process is finished, it will show you the possible solutions to the problem or it will solve it automatically. This way you will be able to know what could have failed and make changes.
The next step you can take if you have not previously solved it is disable IPv6 protocol. Yes, as long as you don’t use it. The safest thing is that you do not need it and you can disable it in Windows to avoid certain problems such as the error to access the DHCP server.
In this case you have to go to the properties of the Internet card. You can directly run the ncpa.cpl command and in Networking uncheck the box for Internet Protocol version 6 (TCP/IPv6), as you can see in the image below. That might fix this bug.
Update card drivers
It is very important to have updated equipment and, without a doubt, the network card is also essential. Problems like the one we are looking at in this article may appear. Perhaps you have recently updated the operating system and there has been some conflict with the drivers if they are out of date.
This problem can especially occur in Windows 11. You have to go to Start, enter Device Manager, Network adapters and select the corresponding card there. You have to click with the second mouse button and give update driver.
Check that the system is up to date
Something similar should be verified in the case of the OS. Do you have it correctly updated? It is very important to install any patch or update available in order to correct certain problems that may appear. In addition to improving performance, you will undoubtedly improve security.
In Windows 10 you have to go to Start, enter Settings, Update and security and there you will see the version you have installed and whether or not there is something pending. In case you have uninstalled files, you should add it and make sure you have the latest versions installed.
In the case of Windows 11 the process is similar. In this case, once in Settings you have to click on Windows Update, which appears below. You also have to make sure that you have installed all the available packages.
See that the antivirus or VPN does not interfere
If you have any installed antivirus or vpn, you can check that they are not interfering. They may be blocking the signal and that is the reason why you cannot access the DHCP server in Windows correctly and you must configure it correctly. Something similar could happen if you have a firewall.
This does not mean that having security programs of this type is something negative, far from it. However, it is true that sometimes, especially when using applications that are not guaranteed, errors of this type may appear.
Obtain an IP address automatically
One more step you can take is to set Windows to get a IP address automatically. Maybe you have it set to manual and that is causing problems. It is easy to configure it and thus you will prevent it from being unable to access the connection normally.
You have to go to Settings, Network and Internet, Advanced network settings, More network adapter options and select the one that corresponds there. You have to click the second button and enter Properties, IPv4 Internet Protocol and again Properties. There you select Obtain an IP address automatically.
All in all, if you are facing this issue to access DHCP server in Windows 10 or Windows 11, you can follow these steps we have mentioned. This will ensure that your computer connects normally to the router and can obtain an IP address without problems.
