What is the best way to restart a down Windows agent remotely?
I have several agents that are stopping for no reason we can tell. I can tell they stop responding, of course, due to the agent monitor, but then starting them again requires that I log in and start them manually. Is there any way to have the zabbix server/proxy send a script to start them? I know the commands to do so, I just am unable to make the connection because SSH is not installed on the thousands of servers we have, and powershell for Linux does not support a decent remoting protocol yet other than SSH; which again, requires an install on each of the machines. Is there another option I am not aware of that would work for this situation?

For any who come across this post with their own search, I just want to say how we worked around the problem. We created a GPO object to set a scheduled task that restarts the agent if it is down. Then in Zabbix, there is a trigger if the agent is down more than 10 minutes, alert. This allows whatever transient issue that takes down the service to restart after it clears, while giving an alert if it doesn't clear to allow time for investigation.
While we would prefer an internal solution (since Zabbix does recognize the agent down, after all); I have yet to hear of one, so this works until we get a better response.
