From Swift Water Software:
Manage all of your windows(2000,XP,2K3,Vista,7,2K8) computers from one centralized console. Gather inventory, install software, manage services or files, run reports and remote control are just a few of the features that are available. DMS works in a distributed environment by connecting the console to all of your DMS management servers, you can get a view of your entire network from one location. DMS integrates easily into your environment with no dependency on external databases. All traffic is done over TCP/IP communication so external access can be done by forwarding just a few ports. Want agent-less management? DMS can optionally manage computers without any software installed on the remote system. All this is available in a small easy to install/configure package.
