For the past few months we've been working with Information Resource Manager at work. It seems to be one of the best open source/freeware database managers for tracking assets and help desk functions for small teams. The lingering annoyance had been slow performance. The more I experimented it turned out the slow performance was only when using Safari/OS X. A quick trip to the /Applications/Utilites/Java/J2SE 5.0/ folder and opening up the Java Preferences allowed me to change the Java settings from 1.4.2 to J2SE 5.0 and all is well.
The latest release of IRM (Yesterday) adds some great functionality for moving printers and other non-computer assets into their own categories.
