Listening interface is easy, but I can't find asking interface option.

I have 3 interfaces on my VM and I don't want unbound to ask from default gateway, is there such an option?

Thanks.

We installed a new Exchange 2016 server and migrated all the mailboxes from the Exchange 2010 server to it. Then we migrated all the mailboxes and public folders from MSEX2016 to Office 365, and we demoted and shut down the MSEX2010. The local AD gets synchronized with Azure AD by the Azure AD Connector on one of our local servers.

This worked for a couple of weeks without problems. All the clien ...

Is my VM under attack or is this an automation gone wrong?
dz flag

I noticed that our Windows Server 2019 VMs, hosted on GCP were often hitting 100% CPU usage, which was odd and started to investigate. It seems that there is an array of PowerShell commands that are running repeatedly that are consuming all the CPU.

These commands seem to scan for user objects with certain names so it's either a GCP guard or some sort of worm/virus. I followed these instructions to  ...

Can google engineers see or access what's within my account's VM, and how can I be sure if this isn't the case? But, assuming that's the case, what tools do your engineers have in case of VM troubleshooting?

NTFS Defrag fails - master file table is too fragmented. (0x89000023)
in flag

Issue: MFT is to fragmented to be defragmented

OS: Windows Server 2016

The goal was to shrink a volume/partition to make room for a separate data section, but the question comes down to: any known solution to this defrag issue/error?.

Is there any known way to get around/fix this MFT issue from within Windows?

I currently only have RDP access to the machine, so this would be preferred.

If not, is there an ...

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.
