MS Visual C++ Runtime Library Error

Many Windows 10 users often change the IP addresses of their computers’ network adapter in order to connect to the internet or network they belong to in times when there is no automatic connection for their computers. In most cases, access to modifying this setting is restricted for some odd reason even if you are an administrator. So if you are one of the users whose Windows 10 VPN IPv4 Properties are not working, this post can help you remedy that so that you can open and edit the IPv4 Properties on your Windows 10 PC. The common way to change IP settings is by going to Settings > Network and then to Internet > Change adapter options > Select Network adapter > right click and open Properties. From there, you can select TCP/IP 4 and modify it. If you aren’t able to do this, refer to the instructions laid out below to troubleshoot the problem in accessing the IPv4 Properties.

Option 1 – Try using PowerShell to manually set the IPv4 properties

As you are not able to set it using the interface, you can do so using PowerShell instead. Note that this option will only work for you if you run PowerShell with administrator privileges. After opening PowerShell, according to many users, you have to run the this command – set-DnsClientServerAddress -InterfaceAlias “Ethernet” -ServerAddresses xxx.xx.xxx.xxx,x.x.x.x,xxx.xx.xxx.xxx,x.x.x.x Usually, Ethernet is the name of your network adapter which is set by default. If you want to see the actual name of your network adapter, you can just type this command and tap Enter after doing so – Get-NetAdapter -physical | where status -eq 'up' After entering the given command, you will see a list of active Ethernet adapter in your computer as you can see on the image above. Note that the 4 sets of X like the one on the image below should match with the sequence:

Option 2 – Try editing the rasphone.pbk files

The rasphone.pbk files stores property for the connections and since you are not able to access the IPv4 properties, it is most likely that it has been disabled here. The good thing is that you can open these files and edit them using Notepad. Refer to the steps below to do so.

• Open the Windows Explorer and then enable the show hidden files option.
• After that, look for the files at this location – C:Users <username>AppDataRoamingMicrosoftNetworkConnectionsPbk_hiddenPbkrasphone.pbk
• Then right-click on it and select the “Open with” option and choose the Notepad app.
• After opening the file, look for “IpPrioritizeRemote” from the long list.
• Once you found it, set its value from “1” to “0”.
• After that, look for “IPInterfaceMetric” and set its value to “1” and tap Ctrl + S to save the changes you’ve made, and then exit and try accessing the IPv4 properties again. It should work, but if you’re still unable to access it, try the next option below.

Option 3 – Enable the Split Tunneling if you use VPN

All data goes back and forth when you are using a VPN service on your computer. And since you are using VPN, it could be that it disables the IPv4 interface. If that’s the case, you need to stay connected with both the local network and VPN and to do so, you have to enable Split Tunneling. How? Follow these steps:

• Open PowerShell with administrator privileges.
• Next, type in “Get-VpnConnection” and tap Enter. After doing so, it will give you the exact name of your VPN.
• After that, type in “Set-VpnConnection -Name “yourVPNName” -SplitTunneling $True” and tap Enter. Once you enter the command, it will free your IPv5 settings so that you can change it to connect with your local network if you prefer it to.

If you encounter an error message saying, “ERR SSL VERSION OR CIPHER MISMATCH” while visiting a website, then it is not primarily your fault as an end-user. In fact, it can happen on any website like Chrome, Edge, Firefox, and even Internet Explorer. Getting this error means that the website you are visiting is using an SSL certificate which your browser seems to be rejected because there is some issue with the certificate. It is also possible that the certificate that’s downloaded on your computer is corrupted or that your computer configuration for TSL/SSL is misconfigured. Here are the complete details of the error message:

“A secure connection cannot be established because this site uses an unsupported protocol, Error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH”

To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error, refer to the options given below and see which one works for you.

Option 1 – Try to access the website with the only HTTP

The first thing you can do is to try accessing the website using HTTP instead of HTTPS. If you can open the website using HTTP then it means that the problem is in the website itself. And if you are the website owner, you can check the following:

• Check if your website’s SSL certificate name is mismatched. Here you need to ensure that the name and alias of the websites match with the actual website URL where the certificate is installed.
• Second, check if your server is using the RC4 Cipher. If it is, then you need to fix that.

On the other hand, you may also check if your CDN also supports SSL since most of the CDN nowadays supports SSL. All you have to do is configure it correctly and it should be good to go.

Option 2 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR SSL VERSION OR CIPHER MISMATCH error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

Well if anyone told me just a few years ago that I will see the day when Microsoft releases a new OS based on Linux I would be very amused, but that day has come. Mariner is the newest OS out of nowhere. Microsoft’s new Linux Distro, dubbed Common Base Linux (CBL)-Mariner, isn’t the type of distro you’d want to install directly on any old machine. It’s primarily meant for cloud infrastructure and edge products. Specifically Microsoft’s Cloud and Edge products. But if you are curious, it’s possible to run. Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide to ISO CBL-Mariner image. With that, you can easily get it up and running. And you can build CBL-Mariner on an Ubuntu 18.04 desktop. So you can try it out since it is free. You can get it from here: https://github.com/microsoft/CBL-Mariner It is obvious that Microsoft aims to set itself as a leader in enterprise server environments with this move and it is very likely that it may succeed or at least give a good shake to its competitors, mainly red hat and Suse which are two dominant distros in that field. Many believe that they can win over by providing regular updates and package delivery via their already established system and that feature could be a turning point for some. In any case, time will tell and we shall see.

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.

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:
