I work as a full time IT/Network Administrator, as well as doing IT consulting for smaller businesses on the side. With Remote Desktop Manager I simply create a folder for each company. RDP, LogMeIn, or Teamviewer, with Remote Desktop Manager it doesn't matter, I am always able to connect with just one tool.
Remote Desktop Manager is one of the most feature-rich remote management tools I know. Aside from helping you organize your Remote Desktop connections, it supports a plethora of protocols and even allows you to administer virtualization solutions and cloud environments.
Devolutions Remote Desktop Manager is a tool that just about every systems admin can use to make their lives easier.
