Once in a while it is expected to get errors like
“DNS Server not Responding” when we surf or working using the
internet. Internet connection failure happens due to many reasons.
Among the various issues one major failure is the 'Domain Name System
not responding'. A DNS server is a computer that serves which
comprises a database of public IP addresses and their related
host names. Mostly DNS serves to resolve or interpret those common
names to IP addresses as demanded.
Devises may fail to join the internet if these
conditions exist. DNS server errors may appear due to many reasons,
for example, a defective internet provider, inaccurate TCP/IP or DHCP
services, proactive antivirus software, imperfect router or modem. One by one, network troubleshooting can be used to
check and correct the obstacle.
Let's start with the simpler ones.
Disable extra unused connections and try with
one
It is an established fact that you can use one
best network connection if you enable only a frequently used network.
Use Any Other Device with the Same Network
You must recognize the error by checking the
network. Connect it to any other system to check your network. When
the internet is connected, obtain the same website to check if it is
available or not. If it is connected, it indicates that your first
system is generating the error.
Solving TCP/IP and DHCP Failures
There is a chance for malfunctioning TCP/IP
software inside the operating system of client's device and set its
DNS server addresses incorrectly. Rebooting computer often clarifies
these momentary flaws. Another method is operating TCP/IP efficiency
programs that deliver the standard procedure to "release and
renew" the Windows IP address settings.
Thus, a majority of TCP/IP networks use the
Dynamic Host Configuration Protocol (DHCP) service to allow IP
addresses to clients. DHCP assigns primary and secondary DNS server
addresses also. If DHCP is not functioning properly, a PC reboot is
reasonably wanted to improve it.
Monitor to secure both your machine and the
network router have DHCP qualified. If each end of the connection is
not utilizing DHCP, internet connection errors result normally.
Managing DNS Provider problems
We usually configure our home networks to obtain
DNS server addresses from their internet provider automatically. When
the provider's servers or network experience an interruption or are
massively burdened with traffic, their DNS services can abruptly stop
working. Customers must remain until the provider settles those
problems before they can use the provider's DNS.
Several free public DNS servers have been
established on the internet by Google and OpenDNS. A router manager
has an option to switch their network's DNS setup over from a private
to a public DNS configuration if they access manually to the public
DNS IP addresses into the router configuration settings.
In critical conditions, administrators can choose
this tentatively or they can make it a permanent change. Through
Network and Sharing Center DNS frames can also be used on the Windows
device itself. Normally this will not work as a stable solution as
devices get and delete their local settings with these from the
router via DHCP.
Avoiding Internet Blockages from Antivirus
Programs
Antiviruses are meant to block trespassing
invaders, but they themselves have the capability to hinder internet
flow once they detect any misbehaving device.
Maximum antiviruses operate using specific
database files that the software merchants automatically update on a
regular base. Computer users usually forget when these install
updates occur as they are triggered in the setting and devised not to
interrupt standard work.
Sometimes data updates cause confusion making the
antivirus program to consider it as malware which is going to affect
the computer. It makes a false alarm or false positive test. This, in
turn, makes the windows to show a DNS server not responding error
message.
To check whether or not it is a virus, pause the
programme temporarily and restart the Windows Network Diagnostics.
After confirming the issue you can ask the antivirus merchants a new
update or you can seek a technical support. Never take antivirus
disabling as a permanent solution as it is not safe.
Recover or Replace a Malfunctioning Router or
Modem
A bad broadband router or modem may become a
reason to show the DNS not responding error messages. Mostly
restarting the router or modem will correct the issue. If the problem
is persisting then it is advisable to renew.
It is very unlikely for both to fail that would
cause DNS errors. Failed routers and modems usually cannot power or
else cause errors related to the underlying network connection.
Now, try to access the
website you previously was checking and see if it works. With the
above solutions, the DNS server not responding error should be fixed.

it.
