I haven't found a commercial tool yet.
If your willing to exercise your scripting skills then a combination of pstools from Sysinternals and Windows reg command line executable in a batch file is where I would start.
Another alternative to explore is monitoring software that allows you to create custom agents. We have configured Nagios to monitor a Windows server environment by deploying custom agents that are essentially windows batch files returning a result to the Nagios monitoring server when called. There might be commercial software that has a lower learning curve you could use.
