Unable to join domain from Site-to-Site VPN Server

I work for a small business that is looking to expand to the cloud so that our remote workers can access more of our systems. As a software dev and keen IT enthusiast, I jumped at the opportunity to get my hands dirty with this project. After spending the last 2 weeks attempting to get a test solution working on my PC with HyperV, I have a new found admiration for networking majors.

ADFS 2012 R2 Cert Replacement
cn flag

I need to change the communication cert on my adfs server. Most docs say that the Communication cert is the same as the ssl cert. We use a DNS alias which is a truncated version of our domain name, and the ssl cert matches that. The old expired communication cert (Which has not impacted anything for 2 years now), was an FQDN cert.

Question. Should I stay the course and replace it as is, or should ...

IIS ARR - Route single request to multiple servers/sites
ng flag
Wes

We have a unique situation with a vendor in which they only allow 1 address for PRD traffic and 1 for Non-PRD traffic. Internally, we need to be able to test in 2 environments (call them TST1 and TST2). Since they only allow 1 URL for TST, I figured I would create 2 ARR Rules for the site to rewrite the traffic to both. I ensured 'Stop processing subsequent rules' was disabled.

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.
