Windows 10: DNS not found only on one computer on one network

My Thinkpad running windows 11 system details at bottom has a weird interaction with my netgear router. The router has two channels, one 2Ghz and one 5Ghz. All other devices, including another windows 11 device, have no problems connecting to either channel. Only my Thinkpad does. Strangely, my thinkpad does not have problems on any other router I've connected to--only this specific one. This is driving me especially nuts, because I cannot identify any general problem with either object. It is something about the overlap between the two.The 5Ghz channel sometimes works for a while but will s

:)

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?

 

Windows 10 - "One or more network protocols are missing" and no DNS server

Hi Tyler,

Thank you for posting your query in Microsoft Community.

Sorry for the inconvenience you are facing. I would suggest you to try the steps below and check if it helps:

Step 1: Reset TCP/IP

One of the components of the Internet connection on your computer is a built-in set of instructions called TCP/IP. TCP/IP can sometimes become damaged or corrupted.

Follow the steps below to reset the winsock entries and TCP/IP stack and to troubleshoot the issue further.

• 
  Press Windows Key + X together and select Command Prompt (admin).
  
• 
  Type the following command and hit Enter after each:
  

netsh winsock reset catalog (reset winsock entries)

netsh int ip reset reset.log hit (reset TCP/IP stack)

• 
  Reboot the computer and check.
  

Step 2: Flush your computer's DNS cache.

• 
  Press Windows Key + X together and select Command Prompt (admin).
  
• 
  At the command prompt, type the following commands. Press Enter after each command.
  

ipconfig /flushdns

ipconfig /registerdns

ipconfig /release

ipconfig /renew

I would suggest you to refer to the troubleshooting steps given in the article below and check if it helps:

dns probe finished no internet


Hi Oxide,

After some trial-and-error testing of all suggested fixes, which I found over the internet, here’re what worked for me to solve "DNS Probe Finished No Internet" issue and might work for you as well.

Method 1: Change Default DNS Address to Open DNS

Here all you have to do is change your default automatically obtained DNS server addresses to open DNS or Google DNS. To do this, follow below mentioned steps:

Step 1: Right click on Network icon located in Windows Task Bar Menu.

Step 2: Click on ‘Open Network and Sharing Center.’





Step 3: Click on Local Area Connection with whom who are presently connected and click onProperties.

Step 4: Select ‘Internet Protocol Version 4 (TCP/IPv4)’ and click on Properties.

Step 5: Now in newly opened windows, select the radio button that reads ‘Use the following DNS server address:’

Step 6: Now in the ‘Preferred DNS Server’ box type in 208.67.222.222 and in ‘Alternate DNS Server’ type in 208.67.220.220.

Step 7: Now check the box that says ‘Validate settings upon exit’ and then click on OK. That’s it.
