I need to run an inventory report on a specific .DLL file for all
workstations at my site. I need the date and version of this file. How
do I get ZEN inventory to grab and store this information to the
database? Or if it's already in the database how do I report on it?

ZENworks 6.5 SP2, workstations running ZFDAgent 6.5 SP2.

Thanks.

Depends on your setup.

But use the following instructions as a basic guide

1. Open "Inventory Service_SERVERNAME" Object
2. Tab "Software Inventory Configuration - Software Configuration"
3. File Software-Mapping -> Edit Table
4. Insert -> Add the appropiate details to identifiy the version.
4.1 You need to know the filename and exact size kb for the min and max
size fields
4.2 You need to know what version matches each file size, thats how its
identified
4.3 Insert new entries based on filename and file size for each version
of the dll.

Hope this helps.
