guys if you are looking for a free tool to manage your connections, remote desktop connections look no further mremote is here.
As you can see I could select the protocol I want and enter user name ..
http://www.mremote.org/wiki/
This tool does not introduce a new protocol or a new way of connecting using the same protocol , but instead relies on putty, terminal services, the gecko framework for rendering web pages, etc which we are already using to connect to remote machines.
All I have to do is create a new connection , select the protocol, enter the user-name and password ... there you go.. u are ready to connect.
All I have to do is right click on the connection and connect.
I have attached a snapshot
