The following is a list of Active Directory Domain Services modules on Microsoft Learn sorted from introductory to advanced. Is there an Active Directory topic that isn’t listed here that you’d like to see covered? (AD CS modules are coming). If you know all this, remember we have the free 45 minute practical Active Directory […]

If you administer Windows, you’re already aware of Windows Firewall. You might use it to allow an application, open a port, or block unwanted inbound traffic. But those familiar tasks only scratch the surface of what it can do. The Microsoft Learn module Understand advanced Windows Firewall takes you beyond basic rules and introduces Windows
Hello Folks! If you run AKS in production, you already know the script. A pod cannot reach an external service, every dashboard says the cluster is healthy, and somebody is SSHing into a node with five browser tabs open trying to piece the story together. This session from the Microsoft Azure Infra Summit 2026 tackles
The setup You’ve built the deployment the enterprise architecture review asked for. Nothing touches the public internet. Your Microsoft Foundry resource is private — public network access disabled, a private endpoint fronting it inside your virtual network. Every resource the agent depends on is locked down the same way: Azure AI Search — private endpoint,
An application starts reporting intermittent timeouts when connecting to Azure SQL Database. Some requests succeed, others fail, and a test from a developer’s laptop works perfectly. The database appears online, no recent deployment seems related, and the natural reaction is to ask: Is Azure SQL unavailable? Is the firewall blocking the connection? Should we increase

Hello Folks! If you have ever spent a long afternoon untangling overlapping CIDR ranges, chasing down a broken VNet peering, or trying to remember which UDR points to which firewall, this MAIS 2026 session is going to feel uncomfortably familiar. Jon Ormond (Principal PM, Azure Networking) brought along Jay Li and Jeff Lovett from the

After working on many Azure SQL support cases, I have learned that the initial service request details are essential, although they may not always provide sufficient information to understand the complete technical situation. When a service request is initially created, the available information may be limited to a brief description such as: The database is
Ask any enterprise team standing up Microsoft Foundry in production and you’ll hear the same non-negotiable: the agent can’t run on the open internet. The moment it touches proprietary data, internal APIs, or regulated workloads, security wants it inside the company’s own virtual network — behind private endpoints, a central firewall, and controlled DNS. That
Last week, I worked on a support case in which the use of the MultiSubnetFailover connection-string feature was being considered for an application connecting to Azure SQL Database. The expectation was that enabling the following option could improve connection recovery during a database failover changing MultiSubnetFailover to True. This option is commonly associated with SQL

Takeaway: Azure Chaos Studio helps organizations validate application resilience by simulating outages, failovers, network disruptions, and infrastructure failures before they impact production. You don’t know with certainty that your application is resilient until that resilience is tested. Better to learn it isn’t by deliberately breaking it in a test environment and watching how it reacts,
