Hi TeleFragger.
Few things in Altiris are free and other things you have to pay a license to use.
What is free in Altiris?
The Altiris Platform (aka. Symantec Management Platform (SMP)) is free to use. You can deploy agents in your computers and execute some tasks such as Run Scripts, Power Control, Get IP configuration, desfragment computers, etc.
Altiris Workflow is also free to use. You can create your own projects and integrate with your SMP.
What you have to pay to use?
Altiris Solutions such as Inventory, Software, Patch Management, Deployment, Monitoring and Real Time System Manager. All of these solutions depends on a license to use. What consumes licenses in Altiris are the solutions, not the agent. If you install a inventory plugin in the agent, will be consumed one inventory license.
Conclusion
You can install a SMP and execute some tasks on your machines without any problem. Of course, you can create an script to install a software, restart a service, etc, but this can be quite harder to do that than use a pre-ready task if you buy the solution. The real Altiris power are on the solutions. To use the solutions, you have to pay for that. To colect a machine inventory, software and image deployment, user migration, install updates from Windows and other solutions, etc.
I'm attaching a link talking about Altiris licensing.
