diskdrives.vbs - vbscript script by ActiveXperts Software

diskdrives.vbs checks all disks on a host.

Use diskdrives.vbs directly from ActiveXperts Network Monitor; in the Manager's 'Monitor' menu, select 'New Check (Script)' and select diskdrives.vbs. Configure the required parameter, or press 'Load a working sample'.

In ActiveXperts Network Monitor, Administrators can use three different scripting languages: Powershell, VBScript and SSH.
