DNS Issue || DNS_PROBE_FINISHED_NXDOMAIN

Question

Hi,

we are using Active Directory DNS services. DNS forwarder pointed to ISP DNS IP address.

issue

when the user tries to access a website its showing DNS_PROBE

steps we followed

we clear DNS in the active directory

we clear DNS in user system

We added a host record in DNS. It's working, (but the public IP on the other side is not static)

We changed the system's DNS to a global IP address (its working )

We connect the system to the ISP and test its working

All other websites are working, but we are facing an issue with one specific website. That website can be accessed from outside.

How can we resolve this issue? What troubleshooting steps do we need to follow?

Thanks

Answer 1

Hello,

Based on my understanding of your issue, I suggest that you open cmd as an administrator on the client and run the following command to force stop the DNS client service in order to completely disable the DNS cache:

net stop dnscache

Then test whether you can access the website

The following command will start the DNS client service:

net start dnscache

If the problem still cannot be solved, it is recommended that you test whether the domain name of the website can be successfully resolved. You can run the following command on the client to check and replace the domain name with the website you cannot access:

Hi,

I ran the following commands, but neither is working in Windows 11 as an administrator.

net stop dnscache

net start dnscache

After that, I used nslookup on a Windows machine, but it was unable to resolve the IP address.

How to resolve the above issue ??

Thanks

Answer 3

Hi,

Thank you for your reply. I suggest you try changing the IPS address of the forwarder to, for example, 8.8.8.8 to see if this can solve the problem.

Answer 4

Dear Zunhui,

We changed the forwarder to 8.8.8.8 it's working. However, when I changed to the ISP DNS IP address, it showed the issue above.

We connected one laptop to the ISP and configured the same DNS. The websites are now working.

According to the system team, they suggest not configuring a global DNS IP address in the forwarder.

Thanks
