While upgrading to Windows 10 1709 Enterprise via WSUS your clients may report the following error:
(Unable to find resource):ReportingEvent.Client.167; Parameters: Feature update to Windows 10 (business editions), version 1709, en-us
This may happen to other versions too

It may happen to receiveDsRemoveDsServerW error 0x5(Access is denied.) in NTDSutil. Here’s my short recipe:
1. Ensure your account has domain admin rights
2. Ensure CMD/NTDSUtil was started with elevated rights (RunAs Administrator)
3. Open Active Directory Sites & Services:
Navigate to the site/server you want to cleanup Right click on the “NTDS Settings” object > Properties > Object
Ensure “Protect object from accidential deletion”
Saves hours of debugging 🙂

Stack Overflow used to run an interesting project –
Stack Overflow Documentation. It is currently shut down, but thanks to it we now have interesting free books like “ PowerShell™ Notes for Professionals book“:
Please keep in mind it was created by SO content that may not be very accurate, like what I’d recently discovered:
Are the cmdlets in a pipeline executing in parallel?
Anyway I’d recommend it since it contains an essentials compilation of PowerShell common tasks and language specifics.Good reading indeed!
There are also other books that may catch your interest:
When you try to add a new vSwitch that is bound to a physical adapter in Hyper-V, you may receive the following error:
[ Window Title ] Virtual Switch Manager for SOME - SERVER
[ Main Instruction ] Error applying Virtual Switch Properties changes
[ Content ] Failed while adding virtual Ethernet switch connections .
[ Expanded Information ] External Ethernet adapter 'Intel(R) 82574L Gigabit Network Connection' is already bound to the Microsoft Virtual Switch protocol .
In this case go to network settings and find the affected adapter. Then in Properties remove the checkbox that binds Microsoft Virtual Switch protocol and press OK.
Try to create the vSwitch again.
Usually you use a usb cable to power and program

But what if you want to use external 3.3V (or 5V) power supply? To which pin should you connect it?

A while ago Jan Almeroth have done excellent research on
how Sonoff devices operate. Thanks to his ( and many others’) work, projects like SonOTA are now possible. I’ll try to summarize the information in this article. 1. Overview
It appears that sonoffs are
IoTgo compatible devices. IoTgo platform was created by Itead and aims to facilitate easier integration between IoT devices and Applications.It mainly consists of three parts:
Devices ⇔ Server (left part) – devices connect to the server via HTTP/WebSocket, register and update their parameters. The server can send control commands using push notifications (via WebSocket);
Apps ⇔ Server (right part) – IoTgo Apps use server gather information about devices (+their status) and control them;
Web interface ⇔ Server (not shown) – used for device management;

Remote switches, Internet of Things (IoT) and Smart home in general are quite trendy nowadays. There are plenty of trademarks and devices that allow you to switch lights, heating, garage doors etc via an application on your mobile / web page.
There is one very popular gadget among the Smart housers – the Sonoff. It is actually a trademark that includes various kinds of remote switches. Sonoff devices are getting more and more popular these days because they are small, cheap, cloud ready, easy to use and have built-in AD/DC converter (i.e. no external power supply is needed, just a cable to plug it in the grid). Some sonoffs can be controlled via RF keyfobs.

Sometimes we need to create users/groups/computers in Active Directory that will be used temporary (by a contractor, for testing etc.). The typical workflow is: Create > Use for a while > Delete. The deletion is manual and often these objects are being forgotten which poses some security risks.
It is little known fact that we can create the so called
Dynamic objects ( DOs, a.k.a. temporary objects) that get deleted from AD automatically when the associated TTL expires. Microsoft added this capability in Windows Server 2003. In fact the “Dynamic object” is an auxiliary class (OID = 18.104.22.168.4.1.1422.214.171.124). When linked to an object it adds some new attributes like the entryTTL (Entry-TTL) and ms-DS-Entry-Time-To-Die attribute.
