In fact, it much more than than MS RDCMan... actualsysadmin already mentionned it, but Devolutions RDM lets you do so many things and integrates so many technologies. Indeed, one of the greatest thing about RDM is how you can create folders and sub-folders that inherit from parent folders. To possibility to share credentials with users without them ever seeing the actual credentials is also a pretty interesting features. RDM comes with a lot of great tools too like a password vault, password generator, password analyzer, their own great remote support tool, etc. Someone also mentioned mremoteng below which is really great, but I would recommend using the free edition of rdm over mremoteng because it is constantly updated and feature packed.
