One of the issues you can run across with systems management tools is doing an automated uninstall and reinstall of the agent software. The dilemma is that you can tell the agent to uninstall itself, but after that there’s no agent software on the machine to run the reinstall command. Most management tools include the ability to scan your network and install agents on machines automatically, but that may not be appropriate for all environments as you may have some machines where you don’t want to install the systems management agent.
I ran across a situation like that recently in my own environment. For details, see below the jump.
