Deploying Microsoft Defender for Identity (MDI) requires more than just installing the sensor on a domain controller. MDI demands careful capacity planning to ensure reliable performance and accurate threat detection. Each MDI sensor analyses authentication traffic, monitors Active Directory activity, and reports telemetry to the MDI cloud service. If the underlying domain controller is undersize… Read the rest “MDI Sizing Tool”
Being able to automate and set Power Plan options via the command is useful for both automation and tasks on Server Core. We can use powercfg.exe to control power plans - also called power schemes - to use the available sleep states, to control the power states of individual devices, and to analyze the system for common energy-efficiency and battery-life problems.
Below are multiple examples of the … Read the rest “Using PowerCfg To Set Server Power Plan From Command Line”
After upgrading Web Application Proxy (WAP) to Windows Server 2019 you may run into an issue with certain applications that are published via WAP to the Internet.
In the below example the AD FS upgrade went well with no issues. The AD FS farm and WAP servers were upgraded to Windows Server 2019 and all appeared to be going well. Too well that was, as when the external tests were validated against… Read the rest “Unable To Access OWA Externally Via WAP 2019”
It’s always DNS. That’s the typical mantra when troubleshooting AD issues.
But what about a fully updated Windows 10/11 machine totally ignoring the DNS server it was told to use via DHCP? Yes, that unfortunately was a recent problem. On the machine it appeared to have the public Google DNS server (8.8.8.8) stuck. Regardless of what network the machine connected to, it ignored the DNS server as… Read the rest “Stale DNS Server Blocking Captive Portal Or Simply Inaccessible”
Reviewing the output of an environement's CAS Namespaces showed that there was an unexpecte URL present for the version of Exchagne that was installed. With Exchange 2013 onwards InternalNLBBypassURL is not something that we need to set. That was an Exchange 2007 and 2010 thing.
In the environment below note that there are couple of things that pique my interest.
Any thoughts?

The amazing Exchange Healthcheck script really has gotten to the point where Exchange Best Practices Analyser (ExBPA) used to be. Exchange admins should heavily use the Healthcheck script. This should be done before and after maintenance tasks such as installing CUs and security updates.
There is a handy dandy shortcut URL to download the script: https://aka.ms/ExchangeHealthChecker

Controlling connections to Azure VMs using the just in time (JIT) policy of Microsoft Defender for Cloud (MDC) certainly improves the overall security of the Azure resource. However, then having to enable JIT on a given VM runs into issues pretty quickly.
Who thought it was a great idea to have “All configured IPs” as the default option? No thanks – I do not want to enab… Read the rest “Quick Tip – Easily Allow JIT to Azure VMs In A Resource Group”
Current versions of Windows come with a version of PowerShellGet pre-installed. The PowerShellGet and PackageManagement modules originally were released in Windows PowerShell 5.0 which itself was part of the Windows Management Framework (WMF) 5.0 RTM. This was back in early 2016. The PowerShellGet module is also integrated with the PackageManagement module as a provider.
The 1.0.0.1 version of Powe… Read the rest “How to Get Newer Version of PowerShellGet – Install, Don’t Upgrade”
Exchange 2019 CU13 has been released to the Microsoft Volume Licensing Center and the public Microsoft Download site! Exchange 2019 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously. CUs are a complete installation of Exchange 2019 and can be used to install a fresh server or to upd… Read the rest “Exchange 2019 CU13 Released (2023 H1)”
Today Exchange 2013 reaches the end of the road and it will transition out of extended support. Hopefully everyone has migrated to a newer version and/or Office 365. But experience tells me that will not be the case.
Hopefully no one will have Exchange 2013 published to the Internet either, but again experience says otherwise…
Please note that Microsoft will not provide technical support, time zon… Read the rest “End of Exchange 2013 Support”
