This is the most obvious and basic remediation action. Within the alert manager there must have some simple way that allows users to reboot a Windows server as the result of trigger condition. This should also include populating a reboot reason in the event log of that server, such that it's obvious who or what rebooted the server.
Sure, this can be done today using tools like psshutdown.exe, or others but this functionality really should be native within the Advanced Alert Manager.
