I have been looking for a multi-purpose network monitoring tool for use at several network customer location and came across a light-weight app called SpiceWorks. Its open source and has a number of nice features. Here is a list of some of the most useful ones
- Schedulable network scans based on domain name or subnet
- Asset classification based on collected data
- Software inventory (including MS patches)
- Basic service/system alerts & monitoring
- User knowledge base portal w/integrated ticketing system
- Warranty lookup for monitored assets
- Antivirus tracking (no AV, outdated defs, versions, etc) for a number of popular packages
