Windows Admin Center (formerly codenamed Project Honolulu) is an evolution of Windows Server in-box management tools. It is a single pane of glass that consolidates all aspects of local and remote server management. As a locally deployed, browser-based management experience, an Internet connection and Azure aren’t required. This article discusses How to set up Windows Admin Center on a Windows Server. Please see How to Install Windows Admin Center on Windows 10 and Windows 11, and how to Test Network Connection to Windows Admin Center Gateway.
Windows Admin Center gives you full control of all aspects of your deployment, including private networks that aren’t Internet-connected.
When installed on a Windows server, WAC provides a centralized point of management for your server environment. By defining who can access the WAC, we are also enhancing the security of our management. It can also be accessed via the web browser and this can also be disabled.
Also, see the following links for “How to setup Windows Admin Center and also how to troubleshoot Windows Admin Center (WAC) access from the Web. For more on Windows Admin Center, please visit this link.
Some points to note before installing WAC
It can be installed on Windows 10 or Windows 2016, and it does not require any agent to be installed on the servers that needed to be managed.
They are managed over Remote PowerShell and WMI over WinRM If you must manage Windows Server 2012 and 2012 R2 Server, Windows Management Framework (WMF 5.1) must be installed. To prepare your environment for Windows Admin Center, see if any of these factors relate to you.
An important factor to consider: Ensure you create a CSR (Certificate signing request) and request a certificate with it from a trusted CA). Preferred Installation type: Gateway Server (Serves as a gateway server and access from any client browser with connectivity to the gateway server). Please download WAC here from this link.
We have other installation types: Below is an image showing other WAC installation type!
- Local Client: Installed on Windows 10, great for quick start and testing
- Managed Server: Installed on an individual Server to have it managed.
- Failover Cluster: Enable high availability of the gateway service.
