Chrome stops opening certain domains without warning. It will open everything else but refuse to open one or several domains. When Chrome fails to open a domain, it will give you the ERR_CONNECTION_REFUSED error. This error doesn't tell you much about what the problem is. It can appear for domains like YouTube. Even if you have visited a domain in the past without any trouble, Chrome will refuse to open it. The simple solution is to use a VPN but if we're being honest, that isn't a solution. In order to fix the ERR_CONNECTION_REFUSED error in Chrome, you need to do a little cleaning. Here's how to fix the problem. Read More

Quickly Switch Between Over 30 Popular DNS Servers From Windows System Tray

"How does the internet work?" You often get asked this question from your non-geek friends who spend half their time on Facebook or YouTube. While understanding every aspect of how it works isn’t as simple, there are certain technologies powering our world wide web that every internet user should know of. One of the them is the Domain Name System or DNS. Simply put, when you type a URL like in your browser’s address bar, it’s converted by your ISP’s DNS service into an Internet protocol understandable by computers and devices connected to the network, which determines how data is moved from point A to point B. Most people use the default DNS provided by their ISP, but if you’re facing issues with it, then one solution is to swap it with another one using a tool like ChrisPC DNS Switch. It’s a Windows tool that carries a huge list of presets from popular DNS servers that you can switch to, and allows power-users to specify custom DNS servers as well. Read More

View All DNS Queries Sent From Your PC With Nirsoft DNSQuerySniffer

Have you ever tried digging deeper into how your computer makes a connection to a website over the internet? If yes, you might already have come across terms like IP address and DNS at some part during your research. The former is a unique address associated with each computer connected to the internet including website servers. DNS (Domain Name System), on the other hand, lets you access these IP addresses using human-friendly URLs i.e. domain names, translating the latter into the former in the blink of an eye. So in short, if you exclude DNS from the equation, you'll need to access each website using its IP address - good luck trying to remember that for every website you visit! DNSQuerySniffer is a new network sniffing application for Windows by Nirsoft that allows you to see DNS queries sent by your system to remote servers, i.e. the websites you surf while using the internet.

Restore Browser Settings & DNS When Changed By Malware

One of the things that many malware and viruses do while attacking the computer is enable dead or inactive TCP/UDP ports to start listening to malicious external requests. This process sometimes involves shutting down browsers' native antivirus security features, which are specifically incorporated to prevent users from like threats. So, unless you deploy a smart malware detection solution, you may not be able to find and remove the bugs that surreptitiously deteriorate your browser's performance. Most antivirus suites are programmed to detect the malware only when they are accessed or moved to main memory as a part of the basic application operation request. Even if it's not loaded into the memory, it can change the browsers' native features that help prevent external attacks. Developed by Anvisoft, Browser Repair offers a robust solution to tackle malware and threats that attempt to change browsers’ native features. As of now, it supports only Internet Explorer, but has some options, which can resolve issues that you may be facing in other browsers as well. Read More

Windows DNS Changer: Switch Between Popular DNS Servers

Domain Name System or DNS provides name resolution for domain names against their numerical identifiers.This is because the Internet maintains two principal namespaces, i.e. the domain name and the IP address system. A DNS Server provides translation between these two namespaces. For example, it is much easier to remember the Domain name, instead of having to remember an IP such as Name resolution by a DNS Server simplifies the task of the end user in terms of remembering the individual IP address, for accessing each website. When you enter a websites URL in the browser’s address bar, this name resolution is provided by your ISP’s DNS server. Read More

Cache DNS Results To Boost Internet Speed With DnsSpeeder

One way to boost internet speed is to use freely available open DNS services. You can switch between different DNS services other than provided by your ISP to check which service provides best results. If switching DNS services doesn’t help, you can try an application which attempts to cache DNS queries to mitigate the time required in looking up IPs of requested domains. DnsSpeeder is DNS proxy server which provides you with just that. It automates the whole process of storing DNS results on your local machine. Being a proxy server, it replaces your primary DNS server address to localhost. When DNS request is received from client, it looks up the IP addresses of the requested domain from local cache instead of fetching required info from your ISP to speed up internet access. In case, it fails to find the IP address of requested domain, it uses certain DNS services to return resolution results back to client. Read More

Perform DNS Benchmarking With Domain Name Speed Benchmark

The Internet is based on IP addresses. Every time you use a domain name, a DNS service must translate the name into the corresponding IP address. For example when you type, DNS translates it in relation to DNS (Domain Name System or Service or Server), translates domain names into IP addresses. As the human brain is far likely to remember a word or phrase such as instead of an IP address. DNS saves us from the impossible task of remembering hundreds of thousands of IP addresses. DNS name servers can have performance and timing issues. DNS resolution either works or it doesn’t. DNS benchmarking tools test the performance of DNS name servers and have the ability to determine whether a particular DNS name server is available, can compare response times of a specific DNS name servers (against publically-available DNS servers), can create a chart (which ranks DNS name servers according to their response times), number of timeouts, and other important parameters.

Windows Server DNS 2003 / 2008 Monitoring Management Pack

DNS (Domain Name System or Service or Server), translates domain names into IP addresses. As alphabetical domain names are easier to remember as compared to IP addresses, therefore, the human brain is far likely to remember a word or phrase such as instead of an IP address. The Internet however, is based on IP addresses. Every time you use a domain name, a DNS service must translate the name into the corresponding IP address. For example when you type, DNS translates it in relation to DNS saves us from the impossible task of remembering hundreds of thousands of IP addresses. Microsoft recently released Windows Server DNS 2003/2008/2008 R2 Monitoring Management Pack. This management Pack (as the name implies), monitors DNS infrastructure health, availability and performance on Microsoft Windows Server 2003, Windows Server 2008 32-bit and Windows Server 2008 R2.
