Tacacs - Free Tacacs Server For Windows May 2026

: Use a Linux-based open-source server (like tac_plus ) inside a Virtual Machine or a pre-built GNS3 appliance if you only need it for lab testing.

: Runs directly on Windows Domain Controllers (DC) or Member Servers without needing Java or web servers.

: Open a command prompt and use: tactest -s [Server_IP] -k [Shared_Key] -u [User] -p [Password] . Other "Free" Alternatives for Windows

: Run the TACACSSetup_v*.exe wizard and set your shared secret during installation.

If you tell me what you're trying to do, I can give you more specific advice: it with Active Directory? Set it up for a GNS3/EVE-NG lab?

While TACACS.net is the most popular native Windows option, you may encounter these:

: Open clients.xml and add the IP addresses of your network devices (routers, switches).

: Edit authentication.xml to create local test users or link to AD groups. Verify Setup : Run TACVerify to check for XML syntax errors.
