I have a Windows Failover Cluster set up with a file Server. There are two nodes and two networks.

Network 1 used for LAN SMB access and Network 2 used for private SMB storage for a bunch of Hyper-V Server hosts that are otherwise not associated with the Failover Cluster.

Network 2 is where the issue is. It's configured with a static IPv4 address 10.10.11.10/24 and the Hyper-V hosts are on the sa ...

What effect does LPIM have on virtual memory

When LPIM is enabled it prevents paging out to virtual memory which causes pages to remain in ram.

My question is:

when LockPagesInMemory is enabled is the pagefile still being used some how or should you just disable the pagefile?

How to generate separate autoreply warning from postfix to senders not using DKIM?

Antispam/phish efforts with DKIM and SPF are weak if they're not widely enforced. I can't turn on strict no-DKIM rejection or emails will be lost, but there should be some penalty for domains not in compliance. Even medium sized recognizeable domains/hosting companies lack DKIM which is troubling.

How can I use nmap against an IPoIB network?

I'm trying to use nmap to check which services are running on a given network but it cannot start just because nmap issues ARP Ping Scans on IPv4 network, and on a Infiniband Network, as far as I know, there's no ARP, because broadcasting is not supported, but you have IP addressing if you're using IPoIB (IP over Infiniband).

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.
