I realize that in Windows 7, it is not possible to save different credentials for the same host, but I need some workaround.
Can I provide the username and password
While trying to figure out how to allow users into our network, without giving them the keys to the castle, I enabled Remote Desktop Access for a few members of my team. Thinking more about this, I quickly remembered a project several years ago while working for the Department of Defense. That project required us to "lock down" access to only necessary personnel and limited access to the programs on the servers. After spending some time on Microsoft's KnowledgeBase, we realized that we could create desktop "shortcuts" for those employees that made the RDP connection, logged them in and limited their access to one specific application on that server.
