For Windows: Enkompass by cPanel

Enkompass is cPanel’s first and only Windows web hosting control panel. Simple yet powerful, the Enkompass interface offers a rich assortment of features that can save your organization time and money.  Designed to be used in a distributed server environment, Enkompass is able to manage many web servers across a Windows domain, allowing for easy automation and maintenance of a set of servers — up to an entire data center.  In addition to the ability to manage multiple servers with one Enkompass install, you get user-based licensing, so you only pay for the users you need. When additional users are required, you can easily upgrade your license. Plus, you can conveniently add web, mail and database servers as your business grows.
