How to Fix Error Code 0x8007267C on Your PC

Error Code 0x8007267C – What is it?

Error code 0x8007267C is specific to Windows 10. This error is triggered when no DNS server is currently configured in your network settings during the Activation process. If you are fairly confident in your ability to address command-line tools and networking issues, you can follow the steps below to try to remedy the error code on your own. If not, you may need to contact a qualified technician in order to resolve the error successfully.

Solution

Restoro box imageError Causes

The cause of Error Code 0X8007267C within the Window 10 system is fairly straightforward. Windows Activation requires a valid DNS server to be configured in order to complete the Activation process; if one is not available or properly configured, then you may see this error code and Activation will fail.

Further Information and Manual Repair

The following methods may help you to resolve this error, but you’ll need to have some familiarity with command-line tools to complete the steps successfully. If these methods do not work or if you are uncomfortable in using the command prompt, you may need to consult a technician to fully resolve this particular error code on the Windows 10 system.

Method 1: Register a DNS server within your network properties and test the connection.

In order to resolve this error code, client connectivity to a DNS server must first be established. The following steps may help you to determine the root problem with your connectivity status:

  1. Open a command prompt, after which you'll run IPCONFIG /all
  2. Verify the following values: The IP address that has been assigned, the DNS server, the subnet mask, and the default gateway. Compare each to ensure that all are set with the values that correspond to your specific environment
  3. Check for basic IP connectivity to the DNS server using the PING command. In using the PING command, utilize the address of the DNS server found in Step 1

ping <DNS Server IP address>

If basic connectivity to the DNS server in question is failing, then you will need to resolve that issue before going further in the process.

After troubleshooting the above basic connectivity issues to the DNS server, you can reattempt Windows Activation by using the command below from within an Elevated Command selection:

cscript windowssystem32slmgr.vbs -ato

If the steps above did not work for you, you may want to try the steps found in method 2.

Method 2: Use phone-based authentication with a MAK (multiple activation key).

If a DNS server is not connected to your network, you can use an alternative method to complete the Windows Activation process. Bypass Method 1 by using a MAK product key instead to activate the volume license installation. Certain MAK product key providers have a variation on the specific key numbers that you will need to use. If you are using TechNet media or MSDN media, you will have to change the product key listed to the product key provided. The product keys provided by either TechNet media or MSDN media for Windows Server 2008 or for Windows Vista Enterprise will be the MAK product key that you will enter in a later step.

Like the previous method, you will need to have some familiarity or confidence in your ability to operate Command Line tools before proceeding. Once you have found your MAK product key, you’ll need to open a command prompt and use the following command to change the product key to match the MAK product key, which should look something like the example below:

            slmgr –ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

After completing the product key change, use the following command to initiate the phone activation wizard, thereby completing the activation of the system:

            slui 04

The activation wizard should be able to walk you through the remainder of the process in a step-by-step manner. In addition to appearing as an error code in Windows 10, this particular error may apply to multiple versions of Windows, including:

  • Windows 7 Enterprise
  • Windows 7 Enterprise E
  • Windows 7 Enterprise N
  • Windows 7 Professional
  • Windows 7 Professional E
  • Windows 7 Professional N

Steps to address the error code may be different in any of these other versions of Windows. If you have difficulty in resolving the error effectively, seek professional technical help.

Best free & paid eMail clients in 2021
Having an eMail in today's modern world is no longer a privilege or being geeky, it has surely become a necessity. From Facebook to LinkedIn or Steam many services today require you to have an account in order to use them, and in order to create an account, you need working eMail. That being said many people today have several eMail accounts, one for social media, one for work, maybe even one for very close friends and family. How creating eMail today is completely free we might end up with several eMail accounts. eMail clients have also evolved much since their first days and became more than just applications for receiving eMails, today they can take various different tasks having additional features built into them like calendar, batch eMail processing, etc. Taking all of said into account I am presenting to you within my personal opinion some of the best eMail clients starting with free ones.

Best free eMail clients

Google Gmail

https://gmail.com gmail eMail clientIt would be very difficult to even start a free eMail list without mentioning Google's Gmail. Introduced all the way back in 2004 as an invite-only service it became over time the most popular email platform largely due to the fact Google is offering free eMail accounts. There are a lot of good things to be said about Gmail itself, most of the area is clutter-free and the largest space is reserved for eMail itself letting users focus on what is important. WEB client itself means that you do not need to have any application installed on your device, altho via Google chrome, you can use Gmail offline offering you flexibility if needed. The ability to connect and manage other accounts like Outlook, Yahoo, etc is just making Gmail even more attractive, and the snooze feature is a really neat little detail that will pause eMail notifications if you need to focus on other things. Lack of organizing messages into folders is a little confusing since Gmail offers its own unique label system but sometimes I need to have old reliable save eMail to folder. All in all, Gmail is a great service and it offers a great eMail on the go experience.

Mail eMail client

https://www.microsoft.com/en-us/p/mail-and-calendar/ mail eMail appFree Windows eMail client simply called Mail is what was once outlook express. Mail itself has the ability to work with other popular accounts like Google Gmail account, Yahoo, iCloud etc. How it comes with Windows OS and it integrates very well with Microsoft Calendar, this eMail client is for many the first choice. On the negative side, I might say this is a strip-down version of Outlook which is paid solution so some features are missing if we would compare the two. Overall, a simple and nice eMail client worth your time, especially if you are on the Windows platform.

Mozilla Thunderbird

https://www.thunderbird.net mozilla thunderbird eMailGreat eMail client matching in functions against paid and premium solutions of big tech companies. Fueled with plenty of customization options and reskinning ones this eMail client offers a lot for its free price tag. It is also fueled by Mozilla community focusing on privacy and security. It can work with any mail service and it is lightweight with a clean look, altho the look itself can be heavily customized. The bad side is that client itself relies on email services to provide cloud-based emails, so if you are receiving your email via a service that does not have a cloud-based service in itself all of your received emails will be locked to the computer where you have received them. Also customizing it can be sometimes a little too technical for the average computer user. All in all, Thunderbird is one great eMail client and it would be a shame not to use it because of its technical side, if you need a reliable and secure eMail client on a single machine, look no further than Thunderbird.

Paid eMail clients

Microsoft Outlook

https://www.microsoft.com/en-us/microsoft-365/ microsoft outlookOutlook comes as a part of the Microsoft Office suite and as one of the oldest eMail clients, it is still widely popular and adopted through many users and businesses. It has tight integration with all Microsoft services and full integration with Calendar making it one of the if not the best eMail client out there. Outlook also has a free online service completely free for personal use as well. The downside is that you can not get it as a separate product if you want a business version other than as a part of the Office suite. The final verdict would be that this is perhaps the best eMail client out but the big downside is that there is no desktop version outside the Office suite.

eM Client

https://www.emclient.com/ em clienteM Client offers a wide array of features, including a calendar, contacts, and chat. Support is provided for all the major email services including Gmail, Yahoo, iCloud, and Outlook.com. The latest version also offers PGP encryption, live backup, basic image editing capabilities, and auto-replies for Gmail. Its automatic system makes it very easy to get emails from other services since there is no manual setting, all that is needed is to type in your email and eM Client will do everything else automatically. A one-time purchase is not pricy and it could offer some features that some free clients are missing. Go check it out with a free trial and see if it is for you.

Mailbird

https://www.getmailbird.com mailbirdThis eMail client's main focus is the simplicity of use with visual appeal while tackling multiple eMail accounts. It has many built-in apps along with a customizable interface. Unlike some more Microsoft-centric email clients, Mailbird Business supports a diverse range of integrated apps, including WhatsApp, Google Docs, Google Calendar, Facebook, Twitter, Dropbox, and Slack, all making for a better-streamlined workflow. The downside of this client is the yearly subscription plan. I think people, in general, want to get away from software subscription plans so I will include this as a downside but bear in mind it is downside just in terms of a business plan not in the client itself.

Inky

https://www.inky.com/ inky eMail clientInky is eMail client if you are looking for security. It uses AI along with machine learning in order to block all types of phishing attacks that can get through to other clients. The proprietary machine learning technology can literally read an email to determine if it has phishing content, and then is able to quarantine the email or deliver it with the malicious links disabled. It also takes things a step further and offers an analytics dashboard, which allows an administrator to see patterns of attacks based on dates, or targeted users. The downside is that client itself is so much focused on security that sometimes some nonsecurity features get overlooked and provide a poor experience but if you need a good and greatly secured eMail client Inky is one to check out.

0x8019019a when setting up Yahoo Mail
The error code 0X8019019A is shown when a user fails to add his Yahoo account to the Mail app due to the outdated or corrupt installation of the Mail app. Not using an App-specific but a normal Yahoo account password may also result in the error at hand. In this guide, we will show you how to effectively fix this error so you can set up Yahoo mail.
  1. Reboot PC

    Perform a restart of your system to rule out a temporary glitch in the system. Also, check if you can successfully access your email through a web browser using the same credentials as you are using with the Mail app. Additionally, make sure that no VPN or proxy server is being used to access the internet (VPN/proxy may work fine with the web version of Yahoo mail but may hinder the access through a mail client).
  2. Update Windows and the Mail App to the Latest Build

    If your system is not updated to the latest build it can create incompatibility between the OS modules. Updating the Windows and Mail app of your system to the latest build may solve the problem.
  3. Re-add the Yahoo Account to the Mail App

    The Yahoo account issue could be a result of a temporary glitch in the communication modules of the system. The glitch may get cleared if you remove and then re-add the Yahoo account to the Mail app.
  4. Reset the Mail App to the Defaults

    You may fail to add the Yahoo account to the Mail app if the installation of Mail itself is corrupt. In this scenario, resetting the Mail app to the defaults may solve the problem.
  5. Generate an App Password and Use it to Add the Yahoo Account to the Mail App

    Yahoo has implemented tons of security features to its accounts. One such feature is the use of app-specific passwords for less secure apps like the Mail app. If your Yahoo username or password is not working with the Mail app, then using the App-specific password may solve the problem.

Not enough USB controller resources Error
As you know, USB is now being widely used in all devices with USB A as the leading type with most devices based on it. Peripheral devices such as Pen Drives, External Hard disks, and many more also use a USB port. On the other hand, USB C is also coming up to be the next big standard in the computing world because of its high transfer speeds, wider compatibility as well as support for external Graphics Processing Units. However, just recently, USB 3.0 ports have been reported to cause the following error to pop up on Windows 10 computers every time a USB device is plugged in.
“Not enough USB controller resources. The controller does not have enough resources for this device.”
To fix this error, here are some guidelines you can check out. Make sure to follow them carefully.

Option 1 – Try to use a lower generation USB port

The first thing you can do is to try using a lower generation USB port as this issue mostly occurs when a device is connected to a USB 3,0 port. This means that you have to plug in your device to a USB 2.0 port and then see if it fixes the error or not. You can easily decipher a USB 3.0 port from a USB 2.0 port as the former is in blue.

Option 2 – Try to use a dock

You could also try to use a dock to resolve the error. Note that when too much power on laptops and notebooks are drawn from the USB ports and as a USB 3.0 port draws more power compared to a USB 2.0 port. Thus, if you plug in your USB storage device into a USB 2.0 port with the help of a dock, it should fix the problem.

Option 3 – Try disabling the xHCI Mode option in the BIOS

  • First, boot your computer into the BIOS.
  • Once your computer has booted, go to the Advanced tab.
  • Next, make sure that the entry for “xHCI Pre-boot mode” is set to Disabled under the USB Configuration section.
