Question : Obtaining all licensing details including product keys for many servers?

A strange request has come through to our team here in infrastructure.  One of the organisations we support would like all the licensing details for the installed software on all of their servers. I am able to obtain a list of the server hostnames and the majority are on the same domain running 2003 in one flavour or another.

I would like to dicuss my options on how to acheive automating this process. Thoughts? Thanks all in advance.

You might be able to use WMI with a batch/vb script during startup to collect this data.

If you have those systems setup with SNMP, you could collect the installed application information and then proceed from there.
