SpaceSentinel

Monitor disk space on Windows drives and shares from any Web browser on your network, or from virtually anywhere with a WAP-enabled cell phone or PDA. If a drive runs low on disk space, SpaceSentinel sends alerts via e-mail, network pop-up message, event log, syslog, or text log file. Installation and auto-configuration can be performed in under 10 minutes for virtually any network with the included QuickConfiguration wizard. SpaceSentinel runs natively as a Windows NT/2000 service, so it doesn't stop monitoring when you log out of the console.

Requirements:

Windows NT/2000

Limitations:

30-day trial
