nslookup is a command-line tool that helps in finding the DNS records of a website. It sends a name server query to the DNS and obtains the corresponding IP address. Aside from that, it can also perform some complex functionality such as finding details about FTP server, Mail server and many more but most of them are used by administrators. The best thing about nslookup is that it queries the DNS server directly and it does not rely on the cache.
On the other hand, there is another tool called PING that is used to verify connectivity. PING sends a packet of information to the IP address or Domain and gets back a response in the form of packets. So if everything goes well, all packets are received but if not, it will help you find out where the delay in the network exactly is. However, the ping command does not always attempt a DNS lookup which means that it might be using the DNS cache and use the IP address available in that table.
Although both nslookup and PING help you in identifying the host or IP address, however, they don’t always work and sometimes fail. So if your nslookup works but ping fails on your Windows 10 PC when querying the IP address of a website then it could be caused by many reasons. It could be that the nslookup queries work for you but when you try to use PING, it fails. For instance, if you open the abc.com website, here’s how it will look like:
nslookup xyz.com
Server: dns.company.com
Address: 192.168.1.38
C:> ping xyz.com
Ping request could not find host xyz.com. Please check the name and try again.
The domain is converted into an IP address and then data is sent to that IP address when you use PING. So when a reply comes back it means that the data is going back and forth to that domain without any problem. However, if the DNS fails to resolve the IP address of the website or if your PC does not attempt a DNS lookup, you will receive a similar error message that says, “Could not find host” and so on. To resolve this issue, here are some options that might help.
Resetting Winsock, TCP/IP, and flushing DNS might help you resolve the issue with nslookup and PING. To do so, follow these steps:
If your computer has more than one NIC connected and there are multiple default gateways, then it will most likely create confusion which is why you need to remove the default gateway from the configuration of all NICs and make sure that there is only one default gateway.
You might want to change your DNS to Google Public DNS as it could also help you in fixing the nslookup and PING issues. To do so, follow the steps below.
You can also try to cross-check the Windows Hosts file to find out if the website you are trying to open has been blocked, because if it is, then it’s no wonder why PING fails even when nslookup works. There are instances when some third-party application modifies the file and adds some websites to the blocklists. So if the website is indeed blocked, you need to remove it from the list.
Deleting the WLAN Profiles might be a good idea if you are not able to connect to the internet on your computer and if you’re using Wi-Fi. It could be that the networks that were connected previously have gone rogue which is why it is not connecting properly. And so deleting the WLAN profiles might help you in fixing the issue with nslookup and PING.

This error is usually caused by a problem in the Local Area Network or LAN. What actually happens is that signals with the wireless LAN are lost or a connection problem occurs within the network cable.
As a result, the 0x80004005 Outlook error is triggered while sending or receiving an email. Sometimes the problem goes away on its own. However, if it recurs after a few hours, it shows that some problem exists within the network.
Also, it is important to understand that different factors can affect the quality of wireless connections in a network.
For instance, garage door openers, microwave ovens, and Bluetooth devices can easily become obstacles, disrupting the connection and causing the quality to degrade. Other causes are listed below as follows.
It is a must to fix this error otherwise potential risks associate with this error such as permanent damage and blue screens.
There are two ways to fix this error and both are listed below as follows.

“Windows Firewall and <Third party firewall name> Firewall are both turned off; tap or click to see available options”.This particular error could be caused by a lot of factors but when you manually check the firewall, you’ll find that there really is nothing wrong with both the Windows Firewall and the third party firewall. So if both the Windows Firewall and third-party firewalls like McAfee, Comodo, and many others are both turned off in Windows 10, then you need to do several things to resolve the problem – you need to check the supporting services that are required and uninstall and then reinstall the third party firewall on your computer. For more instructions, refer to the options provided below.
dir \search term* /swhere search term* is well, what are you searching for. Now if you are looking for a specific file this command is straightforward, you just change search term* with file_name.extension and there you go, but know that this command can be used to be more powerful, for example, you can find all JPG files in your drive by typing dir \*.jpg /s or all files named work by typing dir \work.* /s " * " is a so-called joker sign, it replaces several characters with any in a given string, meaning that dr*s will give you all results with the first 2 letters dr and last one s. Use this to specify better search results and you will get your files in no time.
