I have a school district using Hyena for systems management. It’s a little different than some other tools I’ve seen. In this case, the district uses the Hyena interface in place of AD Users and Computers and performs all tasks from that interface. Additionally, the tool gives them an easy way to stop/start services and remote into machines. It apparently uses VNC and installs/uninstalls that product as the administrator enters/exits the remote machine.
Also of note is the fact that this product is licensed based on the number of administrators using the product (rather than the number of machines to be managed). In our environments, we certainly have a large computer/admin ratio and licensing models like this can be of some benefit. They noted that they paid a few hundred dollars for a license for 3 (I think) admins.
At any rate, I thought it worth a mention in case any of you are looking for a new administrative tool.
