Remote Desktop is the way to gain remote-console access to a windows server, thats the bottom line; however, many of the MMCs available on the console are available as tools you can run from a client workstation and 'connect' to the server you wish to manage, provided you're in the same domain and have administrator rights. Try EventViewer, you can use the pulldown menu to "Connect-To-Another-Machine" many of the other MMCs function in this way as well.
In addition to that you can use both Powershell and VBS to minipulate WMI queries on the remote server as well -- this is more useful for batch processing and other tasks best handled by scripts.
