Disclaimer This article was created based on my personal notes with support from Microsoft Copilot. While Copilot assisted in structuring and refining the content, all technical details have been carefully reviewed and developed by me. So, I’ve got a talk coming up about Power BI Report Server, and naturally, I needed a local test environment to play around with. I figured I’d document the setup here—not just for my own future reference, but maybe it’ll help someone else out there…
