LetUknow   
http://www.mhsoftware.co.uk

LetUknow provides a "peace of mind" method of monitoring your LAN and resources. You can specify numerous jobs and tests in advance on a "set and forget" basis, which LetUknow then runs at regular intervals - you choose how often. If a test fails, the appropriate individuals are notified immediately, via email or network messaging, allowing you to respond to a problem before your users start to complain. You can set up a "ping" test for each server, router or other network component on your LAN and WAN. You can set up "Free disk space" thresholds for all your shared drives. You can set up checks for "maximum folder size" for any folder you desire. You can check that a file exists, or does not exist. You can check UNC path availability. All these tests can be pre-configured, and LetUknow then sits in the system tray and runs them on a schedule you specify. You can specify different users to be alerted to different tests, using differing alert methods. You can view a log of all test conducted, or just those which passed or failed. You can run any or all of the tests with just a mouse click. Tests can be temporarily disabled without the need to delete and re-create them. LetUknow is a "Must-have" utility for anyone supporting a range of IT equipment.
