Solving problems with DNS server while working with Windows® 7
What are the DNS server issues that can occur while working on Windows 7?
Domain Name System (DNS) is the fundamental building block of the Internet. DNS often acts like a phone book and then it will translate the domain name for the purpose of locating and addressing devices on the network. The work done by DNS server is very simple. It will convert the website name which you type in to the IP address. When you type the URL in address bar, the machine will first look for the IP address of the website and after that the page will start to load. DNS servers are the primary element of DNS. The servers are the registered jack which adjoins the DNS. These servers have interact mutually with one another via private network protocols. The DNS networking frame will work according to the server or clients architecture style.
The following points show the different DNS issues and their causes which occur while working on Windows 7:
- DNS server issues
- Faulty delegation of DNS sub domain
- CNAME error
DNS server issues
A DNS server often becomes unreachable due to service stoppage, system crash or due to mistakes in the firewall. An unresponsive server will often cause increases in look up time and will decrease system efficiency. Then, as a result of this issue, DNS queries may stop and you may not be able to access the Internet or your e-mail accounts.
Faulty delegation of DNS sub domain
One of the most common DNS issues is the faulty allocation of a DNS sub domain. This can often result in slow look ups or failure of registering Active Directory services in DNS. As a result of this, you may be unable to access crucial data or keep a record of your PC activities. The response time may also get delayed due to this issue.
CNAME is a common DNS error that refers to the domain name without the IP address. CNAME error can cause look up failures and due to a non-existent server, it will make it impossible for you to access online services. Then when a service is no longer active or when it is moved to a different host then it will result in ghost records and as a result of this, you will not be able to access the old domain controller as it is not on the network anymore.
