Use a DNS server to resolve company subdomains and another DNS for other

This might be an easy thing, but I couldn't find a solution for it.

We have a Widnows DNS server in company which resolves:

How to fix DNS errors on standard Ubuntu 22. DNS_PROBE_STARTED DNS_PROBE_FINISHED_BAD_CONFIG
es flag

I get these DNS errors all the time. Never changed any VPN, proxy or DNS settings on this computer, so all the settings should be standard. But some internets can't connect to DNS. Which DNS server is my computer connecting to? Does anyone know of a working one? It shouldn't be so complicated DNS is just getting IP addresses for domain names. Shouldn't be more complicated then fetching a simple list.

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
