Fix NETWORK_FAILED error in Chrome

I do not know about you, but I prefer to set my Windows to be more to my liking and not how Microsoft thinks it should be. Let’s face it, not all users feel comfortable whit Microsoft settings and idea how things should be. One of the things I particularly did not like even in Windows 10 is icons that come by default on my taskbar, now so far, well until the latest Windows 11 update you could remove default taskbar icons the same way as in Windows 10, just right-click on them and unpin, sadly with latest update build on Windows 11 this option has been removed. In order to remove default icons from the taskbar, one must go now to Windows 11 settings and choose from there which one you would like to be placed on it. Of course, this is nothing game-breaking but it still feels strange why the standard option has been removed, it just makes no sense but lately not many things that come from Microsoft do.

Error 550 - What is it?

Error 550 is an SMTP (Simple Mail Transfer Protocol) outgoing server error code. It usually occurs when you try to send emails through your Outlook account and the email message encounters a relay error. The email returns back without being delivered with a 550 error message. The error message is prompted as either of the following:

"550 Requested action not taken: mailbox unavailable" "550 5 2 1 mail from refused spam site"

In other words, the error code 550 means that your SMTP server was not able to deliver the sent email to the user.

Solution

Error Causes

There are multiple reasons for this error message including:

• The email address was typed incorrectly
• Incorrect SMTP Server settings
• ISP placing restrictions for outgoing mails on the email server
• System infected by virus or malware

Further Information and Manual Repair Regardless of what the reason may be for the error 550 code occurrence, it is advisable to repair and fix the issue quickly to avoid inconvenience. You may not be able to send emails from your Outlook account if the error continues. This can cause great hassle in corresponding with others timely and may create a big communication gap. Here are some quick and efficient ways to resolve this issue on your system:

Solution 1:

There is no need to panic when you encounter error 550. Sometimes the error message may occur because you inserted the wrong/ incorrect email address of the recipient. In such a case, cross-check the recipient’s email address to verify if it is correct. If not, insert the correct address and try sending the email again.

Solution 2:

If the error still persists, try other methods to resolve it. Sometimes error 550 can also occur due to incorrect SMTP settings. Fix it to resolve the error. This can be done by opening your Outlook settings Tools and Accounts option. Now go to view/change the email account for the email account you are having problems with. After that check, the SMTP server is set to mail.yourdomain.com. Then click more settings and then click the outgoing server tab. See if the ‘My server requires authentication for the outgoing server’ is checked. If not, then check on it. Then simply save to confirm changes. Now try emailing again. Hopefully, this will resolve the issue.

Solution 3:

Another reason for the error occurrence can be ISP blockage. When the junk email volumes increase, network administrators (the people who are responsible for managing ISP servers) place restrictions on SMTP email servers to prevent spam on their network. If this is the reason, contact your ISP administrator to resolve the issue.

Solution 4:

Website breaches and stealing user data is nothing new in the world of the internet. Although a very unpleasant experience it still happens even on some high-quality websites. In this article, we will not focus on how can you not be the target of this kind of attack, because you really cannot. Weel you can kind of if you decide not to have your data on websites at all, but let's just say that is not something you are willing to do.

So, in this case, you have some social, forum, or gaming accounts but you heard that service has been breached and that your email or password might be stolen. Well in this case all you need to do is of course to login into the service and change your password. But, what happens if you are not aware at all that service has been compromised?

Mozilla foundation has asked themselves this same question it seems and they have decided to help us out. They have placed a free online service where you can just by typing in your email address find out if your email or data has been compromised in any way.

Go to https://monitor.firefox.com/ and check it out, if you find out that there is some website that you did not know was breached, change your password right away, and if you have used the same password for anything else (I hope not), change them as well.

If you got an error message saying, “Windows could not start the Windows Update service on Local Computer, Error 87. The parameter is incorrect” while you were trying to start the Windows update service on your computer, then this post could help you resolve the problem. Along with this error, you might also get any of these error codes such as 0x80240034, 0x80244019, 0x80070643, and so on. Aside from these error codes, you will also notice that the Windows Update service has been stopped. To fix this issue, here are a couple of suggestions that might help but before you go on, you need to create a System Restore point first.

Option 1 – Try checking Services Dependencies

Dependencies of a Windows Service in Windows 10 are when windows services depend on other services. Such is the case with the Windows Update service – it also depends on three different services such as the Remote Procedure Call or RPC service, DCOM Server Process Launcher, and the RPC Endpoint Mapper. Meaning to say, if two of these services are not working as expected, then the dependant service will also be affected. This could be the reason why the Windows Update service could not start.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter to open Windows Services.
• From the list of Services, look for the following services:
  • Remote Procedure Call (RPC) Service
  • DCOM Server Process Launcher
  • RPC Endpoint Mapper
• After you find these services, double click on each one of them and check whether the Startup type for all is set to Automatic and the Service status is set to Running or not.
• If the service status is not running, then click the Start button. Afterward, check if you can now run the Windows Update service.

Option 2 – Check the Background Intelligent Service and the Cryptographic Service

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Background Intelligent Transfer Service – Manual
  • Cryptographic Service ­– Automatic
• After that, check if the Service status of the listed services above is set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 3 – Reset Windows Update components

If the first two options did not work then you might want to reset the Windows Update components manually. Follow the steps below to reset them.

• Open Command Prompt with admin privileges.
• After that, type each one of the following commands and hit Enter after you key in one after the other.
  • net stop wuauserv
  • net stop cryptsvc
  • net stop bits
  • net stop msiserver

Note: The commands you entered will stop the Windows Update components such as Windows Update service, Cryptographic services, BITS, and MSI Installer.

• After disabling WU components, you need to rename both the SoftwareDistribution and Catroot2 folders. To do that, type each one of the following commands below, and don’t forget to hit Enter after you type one command after the other.
  • ren C:WindowsSoftwareDistribution SoftwareDistribution.old
  • ren C:WindowsSystem32catroot2 Catroot2.old
• Next, restart the services you’ve stopped by entering another series of commands. Don’t forget to hit Enter after you key in one command after the other.
  • net start wuauserv
  • net start cryptsvc
  • net start bits
  • net start msiserver
• Close Command Prompt and reboot your PC.

Option 4 – Run the Windows Update Troubleshooter

If resetting the Windows Update components didn’t work, you could also try running the Windows Update Troubleshooter as it could also help in fixing any issues related to Windows Update including this one. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 5 – Try removing a value from the Windows Registry

If running the Windows Update troubleshooter didn’t help and you receive a message instead saying, “Service Registration is Missing or Corrupt”, you can try to remove a value from the Windows Registry.

• Tap the Win + R keys to open the Run dialog box.
• Then type “Regedit” in the field and hit Enter to open the Windows Registry.
• Next, navigate to this path: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability
• From this path, look for a value named “ThresholdOptedIn” and if you find it, delete it.
• Exit the Registry Editor and see if you can now enable the Windows Update service.

HDMI which stands for High Definition Multimedia Interface is an audio/video interface that can be used to interconnect various multimedia devices. One of the common use for HDMI is when a CPU is connected to a monitor and a projector. Aside from that, it can also be used in connecting Blu-ray players and laptops to televisions as well as monitors. One of the main advantages of using HDMI is that it can transmit both audio and video at high qualities such as 4K using only a single connection. However, you may also experience some issues in using it every now and then and one of them is when you find that after connecting the devices using the HDMI port, the screen appears to be black and there is no audio output. In such cases, there are a variety of hardware malfunctions that could be causing the problem with the HDMI connectivity. Although there a lot of potential causes, there are also potential fixes you can try to fix the problem. Before you troubleshoot the HDMI Port problem, you might want to perform System Restore first as it might help you in fixing the problem. It could be that you’ve made some changes in some of the settings in your computer that triggered the problem. Thus, you can try run System Restore to undo them, refer to these steps:

• First, press the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the Stop error is fixed or not.

If the problem still persists after System Restore, then follow the given options below to further troubleshoot the problem.

Option 1 – Try to physically check the hardware of your computer

The first thing you can do is to check the physical status of the hardware in your computer. You can clean the dust off the hardware components like the Network Card or Graphics Card of the computer. You might want to use a small blower or you could also use a soft cloth and run the components gently. Make sure that you don’t damage any parts with moisture or cause harm to any circuits while you carry out this task.

Option 2 – Run the Video Playback troubleshooter

You might also want to run the Video Playback troubleshooter. To do so, refer to these steps:

• First, open the Windows settings app.
• Then navigate to Update & Security > Troubleshoot.
• From there, scroll down until you see the Video Playback section and click on it.
• After that, you’ll see the Run the troubleshooter button, click on it to run the Video Playback troubleshooter, and follow the next on-screen instructions.

On other hand, you can also run the Hardware and Device troubleshooter if the Video Playback troubleshooter wasn’t able to fix the problem. You can run it from the same page that you run the Video Playback troubleshooter.

Option 3 – Try to rollback, update, or disable the Graphics card drivers

To fix the problem with the HDMI port, you can either roll back, update or disable them depending on your preference in order to resolve the problem.

• First, boot your computer into Safe Mode.
• After that, tap the Win + R keys to launch Run.
• Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
• After that, a list of device drivers will be displayed. From there, look for the Display Adapters and click on them.
• After that, right-click on each entry under the Display Adapters. Note that the rollback option is only available if the update was recent. So if it isn’t there, just click on the Update Driver option.
• From there, Windows will automatically check for problems and update the Graphics card drivers.
• Now restart your computer.
• After restarting your computer, go to the Settings app and Check for Updates in the Windows Update section.

Note: You also have the option to go directly to the website of your graphics card manufacturers like NVIDIA, Intel, or AMD and go to the section called Drivers then check if there’s a new available update – if there is, download and install it.

Option 4 – Try to reset the Monitor

You could also try resetting the monitor or television using its hardware keys and see if it can resolve the problem. You can just refer to your TV or monitor’s guide for more information on how to reset them.

Option 5 – Try some miscellaneous fixes

Apart from the four given options above, you can also check out some miscellaneous fixes to fix the HDMI connectivity issue and here they are:

• You can try to plug out the HDMI cord/cable from both source and destination and then plug it back in after a couple of minutes.
• You can also check if the HDMI cable you are using is still in working condition.
• You can also try to change the source and the destination of the video and see if either one of them is in a non-workable state.
• Try checking if your settings are how they should be as intended in the “Project my screen” option by tapping the Win + P key combination on your keyboard.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

Windows 11 is getting adopted more and more each day, and how more and more users are installing it some smaller bugs show up. One of the things that have manifested lately is that in some cases installation assistant is not working throwing error 0x8007007f at you while you try to finish the update of Windows. If you are one of the users that are experiencing this kind of annoyance, we have a solution for you. Follow this guide as presented and repair this annoying error.

Run installation assistant as administrator

This is the most simple solution that can solve problems right away and it is advised to be tried first.

1. Download standalone Installation assistant installer from Microsoft website here
2. Go to the location where you had the file downloaded
3. Right-click on file
4. Click on Run as administrator
5. On the permission box, click YES

Disable antivirus and/or firewall software

Antivirus or firewall software can sometimes interfere with Windows’s update and prevent for any reason download or installation of files they consider not safe. If the first solution has not provided success turn off your antivirus or firewall software and try again to install updates by running them as administrator. Now, how many different antivirus or firewall applications are unique pieces of software it would take too much time to cover all of them but usually and most commonly if you right-click on the taskbar icon of security app most of the time you will have either option to open it and close it or simply just to snooze it for some time.

Set the compatibility

If you are still having issues with installing updates try setting compatibility mode for the installer.

1. Download standalone Installation assistant installer from Microsoft website here
2. Go to the location where you had the file downloaded
3. Right-click on file
4. Click on properties
5. Go to the Compatibility tab
6. Click on Run this program in compatibility mode for:
7. Choose Windows 7
8. Click on APPLY
9. Run installer

Run SFC scan

If you are still facing installation issues there is a high chance there is something wrong with Windows system files. Luckily Windows itself has a built-in tool to address these issues and fix them.

1. Open command prompt as administrator by pressing Start and searching for the command prompt and then on right-clicking on run as administrator
2. Once the command prompt opens type in SFC / SCANNOW and press ENTER
3. Wait for the whole process to complete and then restart your system

Microsoft sent an email to users on the Dev build channel saying that the company intends to push some builds that don’t represent what consumers will receive with Windows 11 when it officially releases. In other words, these are going to be some rather buggy builds that won’t be too enjoyable to use. The company recommends users switch from the Dev to the beta channel if they aren’t prepared to deal with the instability. We’ll have to wait and see just how buggy these builds are, but if Microsoft is actually sending out a warning about them it is very likely that builds will be plagued with issues and maybe even stability problems.

Back to Windows 10

How we can expect some buggy build of Windows 11 if you prefer a stable system over new features maybe best decision would be to switch back to Windows 10 until the new OS hits official release.

Switching from dev build channel to beta channel

Another solution, if you do not want to deal with too many issues, is to switch from Dev build channel to beta where things will be more stable. Follow the guide below in order to quickly switch to the beta channel. Following instructions only apply to Windows 11 installations that are linked up to the Windows Insider program, not clean installation of OS.

1. Press ⊞ WINDOWS + I to open settings
2. Inside settings click on Windows update
3. In Windows Update click on Windows Insider Program
4. Inside click on Choose your Insider Settings
5. Click on the button next to Beta Channel to select it (you can switch back to the Dev channel here if you change your mind)

The setting will be saved automatically and from now on you will only receive beta channel updates.

As you know, the Windows Firewall is designed not just to protect your computer from viruses and malware, and other security threats but it’s also designed to block any program from accessing the internet. Users are given the option to block both inbound and outbound traffic for any apps on their computers. However, this kind of option can often lead to not being able to access the internet. In such cases, when you try to run the Windows Firewall Troubleshooter or the Windows Network Diagnostic troubleshooter, it will throw an error message that says, “Windows Firewall is preventing connections to your computer. The Windows Firewall rule HSS DNS Leak Rule may be blocking your connection”. If you are in this kind of scenario, then you’ve come to the right place as this post will guide you on how exactly you can fix this error. When you encounter this kind of error, there are several options you can check out to fix it. You can try to allow an app or feature through the Windows Firewall or uncheck the HSS DNS leak rule in both private and public. For more details, refer to the suggestions provided below.

Option 1 – Try to allow an app or feature through Windows Firewall

The first thing you can do to get rid of the error is to allow a feature or app through the Windows Firewall. To do this, follow these steps:

• Open the Windows Defender Security Center.
• From there, select the Firewall and Network Protection option.
• Next, click on the “Allow an app through firewall” option and then click on the “Change Settings” button and make sure that you have administrative privileges.
• After that, select the app or feature you want to allow through the Firewall from the menu. You also have the option to manually add the app by using the “Add an App” option.
• Then select the between the type of network an app can access such as:
  • Private Network will allow the app to connect to the internet only at home or work.
  • Public Network will allow the app to connect to the internet from anywhere, including Public WiFi hotspots.

• Once done, restart your computer and see if it fixed the error or not.

Option 2 – Try to uncheck the HSS DNS leak rule in both private and public

The next thing you can do to fix the error is to uncheck the HSS DNS leak rule in both private and public. You can do this by following these steps:

• Open the Windows Defender Security Center.
• From there, select the Firewall and Network Protection option.
• After that, click on the “Allow an app through firewall” option and then click on the “Change Settings” button and make sure that you have administrative privileges.
• Next, scroll down until you see the HSS DNS leak rule in both private and public option and then uncheck it.
• Now restart your computer and check if the error is now gone.

2021 is nearing toward the end and with just a couple of days remaining in this year, we are happy to look forward to the next year. So in large anticipation of what will next year bring us, we are taking a good design look at this one and making a list for you of what graphic design software you should learn and use in the upcoming 2022.

Before we dive into it in more detail and predictions please be aware that this article is based upon my personal opinion drawn from the research of current trends and standards. That being said let's dive right into details.

Adobe Photoshop

Whether you like it or not, Adobe has cemented itself with its flagship application Photoshop and how things are looking this situation will not change any time soon. Photoshop is an extraordinary pixel manipulation software that has the ability to work with both animations and vector graphics as well making it a great single application for all-around design needs. It has been industry-standard design software for the web, print, and all other kinds of design all over the globe and this will not change in near future. With its constant updates and expansion of its abilities, this is a must-have tool in your design tool belt. If you are looking to find work as a designer you will have to know how to work with photoshop.

Adobe illustrator

Many will tell you that is photoshop for raster graphics, the illustrator is for vectors. First started as illustrator 88 on Mac right away it took first place for vector graphics from FreeHand and it continued on its path of vector dominance. After some time and more integration with photoshop Adobe managed to overthrow Corel Draw as well winning the title for best vector editing software with illustrator. Same as with photoshop, if you are planning to work in a serious industry you will need to know the illustrator.

Adobe InDesign

We are still in Adobe train and it is moving hard, InDesign is graphic design software aimed for paper publications. If you need to create and prepare any kind of professional publication for printing InDesign is the application to go to. With its specific print aimed features it is a must-have for any graphic designer.

Corel Draw Graphic Suite

Once the king of vector and print design but dethroned by Adobe Corel Draw still has some punches to stay relevant in the field. With some cool features like symmetry and long shadows, it stands out from its competitors for its ease of use. Corel was always focused on easy to learn, and difficult to master and it is still following that kind of thinking. Granted not many employers will require you to be a master of Corel Draw but some of them will request that you are familiar with the application. One of perhaps the greatest advantages of Corel over Adobe is not locking you into a subscription making Draw suit a great choice for freelancers and designers that want to own software, not rent it.

Affinity Designer

The first software from Affinity was Photo, made as a cheap version one-time purchase competitor for photoshop. Later it has released Designer, also a one-time purchase competitor for illustrators. If we are going to take a good look into a feature for feature comparison, both Adobe and Corel will win over Affinity but if we take a look at a price that is a one-time purchase Affinity will win over easily. Priced only at $54.99 it is a steal, and taking into account that many designers will not require any very advanced features found in Corel or Adobe applications Affinity is the way to go.

Inkscape & GIMP

Speaking of price, nothing beats free, and both Inkscape and GIMP are completely free. offering very decent and competitive features applications will require you to get used to their own specific UI and workflow, but once you get a grasp of them, you will be able to do most design work in them. One of the downsides of using these free open source apps is their limited export options but if all that is required from you is to deliver a typical SVG, JPG, EPS, PNG, or PDF file you are good to go.

Colorcinch

Free with basic functionality with the option to purchase more advanced features Colorcinch is a great application if you are on quickly developing and creating graphics for social media posts. Add quickly text or filters, quickly do the color adjustment and save for social apps. The application also within its basic boundaries can work directly on the website without you requiring to even install it making it one of a kind. Go try it at the official site and enjoy yourself.

Conclusion

If you have followed the graphic design scene you will notice that nothing has changed and it will not change in near future. This just speaks about how much industry is defined and how little change is there over time. I advise if you can to get and learn adobe suite since it is industry standard and is required from almost every employer today. Rest applications on the list are great alternatives and can bring you income and offer you a way to finish your project.
