Microsoft have finally released a public version of this great tool. Download.
If you work with a lot of remote desktops, this tool will be an invaluable productivity boost to you!
“RDCMan manages multiple remote desktop connections. It is useful for managing server labs where you need regular access to each machine such as automated checkin systems and data centers.
Servers are organized into named groups. You can connect or disconnect to all servers in a group with a single command. You can view all the servers in a group as a set of thumbnails, showing live action in each session. Servers can inherit their logon settings from the group. Thus, when you change your lab account password, you only need to change the password stored by RDCMan in one place. By default passwords are stored securely by encrypting with CryptProtectData using the (locally) logged on user’s authority. Servers can be moved between groups using drag-and-drop or via their properties page. “
