The Dynamic Host Configuration Protocol (DHCP) server handles automatic IP address assignment within a company network. This article explains how to transfer the DHCP server role to Windows Server 2025 using PowerShell, covering the export and import of DHCP scopes, leases, and reservations to facilitate a seamless migration with minimal disruption to users and systems.

OpenAI has just released its first open-weight models, gpt-oss:20 and gpt-oss:120, enabling you to run these surprisingly powerful models locally, which benefits security and privacy. I downloaded gpt-oss:20 and tested it on my laptop using Ollama and within VS Code with GitHub Copilot. To my surprise, the 20 billion parameter model gpt-oss:20 responded to my prompt.

In Edge Copilot Mode, announced a few days ago, Copilot shifts from being just an AI assistant to becoming the main browser interface. Now front and center in Microsoft's browser, Copilot has evolved into a serious ChatGPT competitor. In this post, I explain how to enable Edge Copilot Mode and discuss whether it introduces any new features compared to the previous version of Copilot in Edge.

If you forget the root password for ESXi, VMware recommends reinstalling ESXi. In smaller environments without automated rollouts and central profiles, you must then configure all settings manually. Alternatively, you can reset the password using an unofficial method.

Windows-MCP is an open-source MCP server that enables AI agents to control the Windows operating system, supporting tasks such as file navigation, application launching, and GUI automation. It features mouse/keyboard input tools, clipboard management, and window and app state detection. I tested Windows-MCP, one of the extensions listed in Anthropic Claude Desktop that can be installed using the free plan.

Grafana offers enterprise-grade Microsoft SQL Server monitoring without the high licensing costs, making it ideal for comprehensive database observability, proactive database health monitoring, troubleshooting, and capacity planning. In my previous blog, I explained how to install Grafana 12 on Windows. This post will outline how to connect Grafana to SQL Server for real-time monitoring.

Reports indicate that ChatGPT Agent Mode might be capable of solving CAPTCHAs, which are often the final line of defense against persistent bots like AI crawlers on many websites. However, these claims originate from Reddit, known for the frequent hallucinations of its users. To verify, I decided to test it myself.

The new ChatGPT Agent Mode combines the Operator's ability to browse and interact with websites with Deep Research's ability to analyze and synthesize information from multiple sources. I tested ChatGPT's Agent Mode and was quite disappointed. Honestly, I find it surprising that OpenAI made this feature available to the public, considering that they have led the way with their chatbot so far. In my view, ChatGPT's Agent Mode is a flawed concept because it forces an AI agent to use a web browser, a relatively primitive tool designed for inferior human intelligence.

The Network File System (NFS) is a widely used file-sharing protocol in Linux environments. However, many Windows administrators may not know you can mount an NFS share easily on Windows 11 and Windows Server. This guide shows you step-by-step instructions on activating NFS for Windows and mounting a share using PowerShell.

Are you skeptical about AI? Do you believe that AI is overhyped? Then, the latest episode of the Big Technology podcast is for you. AI champion Alex Kantrowitz and fierce AI critic Ed Zitron tackle the gap between AI hype and reality. However, both prominent journalists overlook an essential aspect when assessing AI's economic potential.

NFS is a practical solution for copying data between Windows and Linux systems. It is particularly useful for managing heterogeneous networks. This post will guide you through installing an NFS server on Windows Server 2025, creating an NFS share, and mounting it from Linux or Mac.

I tested three MCP servers in Anthropic Claude Sonnet 4: Claude Gmail Search, Zapier Gmail MCP server, and GongRzhe’s Gmail MCP Server. I also submitted the same search prompt to Gemini in Gmail. The results varied greatly. Only two AI tools passed my test, one failed, and the most promising MCP server turned out to be useless.

Migrating a Hyper-V host from Windows Server 2019 Core to Windows Server 2025 requires attention beyond just the virtual machines. The host's configuration is equally essential and includes network cards, vSwitches, and default paths, all of which need to be transferred accurately. Using Windows PowerShell, you can export key settings and restore them on a new server.

Anthropic has introduced two new concepts for connecting AI models to resources through MCP: desktop extensions and connectors. Extensions are available only on Claude Desktop (Windows and Mac), while connectors are supported on both the desktop and the Claude.ai web app. All desktop extensions are local MCP servers, but not all local MCP servers qualify as extensions. Conversely, all remote MCP servers are considered connectors; however, not all connectors are remote MCP servers. Although some theoretical documentation about these new concepts exists, I mainly categorized them based on how Claude Desktop organizes the different types of MCP servers.

Microsoft has released AI Shell v1.0.0‑preview.5, which provides a Windows-only security patch, while Preview 4 delivered substantial improvements—enhanced macOS side‑pane support in iTerm2, Entra ID authentication, expanded Invoke‑AIShell functionality (with new -PostCode, -CopyCode, and -Exit flags)—all based on community feedback to improve workflows across Azure OpenAI, macOS, and PowerShell. This article also explains how to install Microsoft AI Shell on macOS.

Windows Server 2025 can run Windows and Hyper-V containers. The former share resources like the kernel with the host OS and have process-level isolation, while the latter run in virtual machines. To enable communication between containers and with physical systems, you must configure the network accordingly.

VS Code version 1.102 introduced several useful new features in GitHub Copilot. Command allow/deny lists let you specify which commands the Copilot agent can execute without asking for permission. The resubmit feature enables you to edit a previous request and resubmit the prompt. Additionally, the new VS Code version includes various updates for managing MCP servers, including a curated catalog of MCP servers.

A new study by METR got a lot of attention online. It claims that developers often overestimate the productivity boost from AI tools. In a coding test, the researchers found that AI caused a 19% "slowdown" for developers. In my opinion, it's not AI coding that's overhyped, but rather the study's findings.
