We use ZEN to query the database and get some info about the devices etc
in our network. However it seems the data is not alway right, it does not
display every device in our network and some info about some devices are
missing (serialnr, strange mac addresses etc)Does anyone know how the
query/database works? I have to build an intranet application that also
has to "communicate" with the database to read info about the devices
(attached monitor, mac address, type, serialnr, user etc...). But I have
to know the "rules" how the database deals with these querys and the
change of information.

Does somebody know this? Because it does not look very consistent to me,
and ofcourse it is!

Thank you in advance,
