Remote Desktop with Azure AD Application Proxy

I have set up an RDS deployment exactly like its outlined on Microsoft documents, and tried to publish it with Azure AD Application Proxy. But all I receive is the IIS welcome page when browsing to the external url, so apparently I have not done something right. Does anyone have experience with this?

Port forwarding with wireguard
us flag

Using applications like qbittorrent and airdcpp to share files. They all need some ports to be forwarded in order to be "connectable".

In the home connection I would go into the router settings 192.168.1.1 and then forward the ports, ex. 56000 to my PC's local ip address: 192.168.1.124. And the services would work alright.

Later set up wireguard on a Linode VPS wishing I can vpn into it and and mask  ...

Is there a way to remotely see the progress of windows updates
gg flag

We have to roll out upgrades from earlier versions of w10 to 20H2 in our environment and WSUS is generally being WSUS. It's difficult to tell windows update to do something on demand. Our GP is set up as best as we can and does the job, but it can be difficult to get a picture of what is happening at any exact moment.

I've discovered quite a few powershell tips to get a better picture of what's g ...

Windows clients slow to open SAMBA on Debian 10 (when using short hostname)
cn flag

I'm having a strange problem for windows 8 and 2012R2 clients, which use a Debian 10 samba server in ADS mode. The issue is slow initial directory listing of the server, only when using the server's short name i.e. "\server"

If clients use \server.mydomain.example or \Server_IP_Address connections are very fast. If they use \server the connection takes between 1 and 30 seconds to show the initial ...

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.
