Workstations disappear from inventory

Within the last couple of months, we upgraded from Zfd3.2 to Zfd4.01. When
I checked on the inventory process, I found it wasn't working. Since I had
an available Netware 6.5 server, I set it up from scratch as a fresh new
4.01 Inventory server.

I thought I had the process working. However, the database doesn't seem to
grow over time but start over. When I checked on it yesterday, I had over
50 workstations included and expected to have over 100 when I checked today.
However, today I only have 7. It's is as it starts fresh each day and
doesn't append.

I haven't had any luck searching for TIDs.
