TL;DR: Got new server running Win2019. Went to move VPN over from Win2008R2 server. When 2019 connecting to 2019 server, clients get the old and common error: enter image description here

But connecting to the existing 2008R2 VPN, they can connect fine.

Adapter VMQ and processor groups in Hyper-V (using Switch Embedded Teaming) not working

Is there any NATIVE disk monitoring solution for storage in Azure VMs?
bd flag

I have done plenty of digging, but it looks like this may be a shortcoming in Azure. I cannot find a native solution in the Azure portal to tell me when VMs are running low on disk space. What if I want to simply run inventory on my VMs to see how much space is being used on any attached drives? Nope.

For now I am piggy-backing on my 3rd party server monitoring agent for this, but in my situatio ...

What's the correct way to set the time on ESXI hosts?
cn flag

I tried doing it through cli with the following command:

esxcli system time set -d 3 -M 11 -y 2021 -H 14 -m 10 -s 0

But after restarting a guest OS (Windows), the time on it resets to the wrong one again (1 hour late in this case).

Google Cloud metrics
tr flag

I'm running some servers with a docker container.

Recently I've seen that disk space on my root disk (inside docker) is getting low. That disk is "mapped" as /mnt/stateful_partition in the physical machine.

I've searched for big files in the physical disk and I've found one that puzzles me:

/mnt/stateful_partition/var/lib/metrics/uma-events

That file keeps growing evey day (roughly 5 MB a day) and ...

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.
