How to fix the dns server not responding error
Today, one of my colleagues had a problem with a Windows Server 2008 R2: Name resolution on a Debian client was incredibly slow after configuring the server as the DNS server for the local domain. A ping only took a few milliseconds to return the correct IP, but a few seconds passed between each ping:
All worked fine after I added -n (disable address resolution) to the list of ping options. As a result, it had to be a DNS server problem. Volker Helms seemed to be having the same issue, and his blog post pointed me in the right direction.
While the client attempted to resolve a host in the DNS server’s own DNS domain, the DNS server attempted to forward each DNS request to a root server on the internet that it could not access (due to firewall settings). The ping worked perfectly after adding the root zone (.) to the DNS server. But, because I thought this was a poor option, I looked for a better one and came across the following: Advanced – Server options (Properties – Advanced – Server options) – Disable recursion (for more details, see Microsoft’s Disable Recursion on the DNS Server). The ping functioned as planned after activating the environment.

The /etc/resolv.conf file on the server was to blame. DevOps modified all of the hosts’ resolv.conf files to include a search line, which was picked up by the Docker containers when they were restarted.
As a result, attempts to link to http://my-service:12345/api/v1/health were made as my-service.local.company.com (timeout), my-service.company.com (timeout), and finally just my-service.company.com (timeout) (API success).
Then, in the container entries, I built a volume for docker-compose to mount./resolv.conf:/etc/resolv.conf. This overrode the host’s resolve.conf, and all internal service names now resolve easily and without timeouts or delays.

There have been no modifications that I am aware of.

I’ve flushed DNS many times.

Yes, the wireless network bypasses the server and connects directly to the router. So, on a wireless network, you’d get the DNS information sent by the router, while on a hardwired network, you’d get the DNS information sent by the on-site server. I’d love to be able to send anything via the router, but that would mean we’d be unable to use Active Directory logins.
According to my understanding, they decided to limit access to the sign controller to only one computer. They didn’t want it linked to the main network, so they hired someone to hack our network and change the sign (we rent our hall). That NIC is a static IP that only connects to the sign controller and has no internet connection.
On the server, IP6 has been disabled. On the workstation, I’ll take care of it. I’ve made sure the Auto Detect is turned off. The root hints would be unchecked. When I ran the DNS Stress test, I found that some of the root hints were failing. Our modem is an SB6190 with software version 9.1.93N installed. The modem belongs to us.

For our network applications, we all need proper DNS resolution. Let’s face it, when DNS resolution fails, doing something that has to do with networking on your machine is a pain because there’s a decent chance it won’t work. DNS isn’t just a “good to have” on a network; it’s a necessity. As a network administrator, I’ve heard end users complain that the network is down when, in fact, the DNS servers are to blame. In these situations, I assure them that the network is operational, but the DNS servers are unavailable! As you would expect, this does not sit well with them because, to an end user, it all looks the same. DNS stands for “the network” (not that they know what DNS is anyway).
So, if DNS isn’t resolving a DNS name on an end user PC (or your PC), how can you troubleshoot this vital network infrastructure service? Here are ten tips and tricks to get DNS running again that I suggest you try…
If you open your web browser and type in a URL that doesn’t pull up a website, you may mistakenly blame DNS. In fact, your network access is much more likely to be the source of the problem. This is particularly true if you’re using a laptop with wireless networking. With wireless security protocols, the key must be renegotiated on a regular basis or the signal intensity will deteriorate, resulting in network communication loss. Of course, network access can be lost on any kind of network.
