Ah... When most people refer to "Languard" it's usually for their network scanning product and is well-known for that. There are, however, specific variations of Languard:


GFI LANguard Security Event Log Monitor (S.E.L.M.) performs event log based intrusion detection and network-wide event log management. GFI LANguard S.E.L.M. archives and analyzes the event logs of all network machines and alerts you in real time to security issues, attacks and other critical events.
GFI Network Server Monitor automatically monitors your network and servers for failures and allows administrators to fix and identify issues before users report them. Alerts can be sent by email, pager or SMS.
GFI LANguard Network Security Scanner (N.S.S.) checks your network for possible security vulnerabilities by scanning your entire network for missing security patches, services packs, open shares, open ports, unused user accounts and more.
GFI LANguard Portable Storage Control (P.S.C.) offers you network-wide control of which users can use removable storage such as USB sticks, CDs, floppies, smartphones, MP3 players, handhelds, digital cameras and more.
Each one is seperate so perhaps you can identify which one you were thinking of (I'm going to guess the first one). You might want to look into Tripwire, which is the closest other product I've seen that would come close to the Server Event/Server Monitor. That might be something to try and see if it matches.
