If you have a lot of servers that you connect to remote desktop, then this tool is for you. You can organise your servers into a folder structure, set up default connection settings on folders that are inherited down to each connection, and save login details (encrypted against your user account).
Then you can connect all servers in a group at once, see (and interact with) many screens at a time, or switch between servers easily. Basically makes having multiple RDP connections much easier.
You can download the tool from http://www.microsoft.com/en-us/download/details.aspx?id=21101 or read more at http://blogs.technet.com/b/exchange/archive/2010/06/11/3410093.aspx
