Office Inventory Tool v2.0

Hi,

I'm trying to inventory the systems on our network using the Office
Inventory Tool. I set it up on a server, but when I run it, I don't get any
valid info in the report. The XML output looks like this no matter what
system I scan -

?xml version="1.0"?
INVENTORY DETINFODATE="2004-05-06" DETINFOBUILD="11.0.0.6506"MACHINE
NAME="ADMIN_1"ERROR CODE="-1"Incomplete detection
information/ERROR/MACHINE/INVENTORY
!--This scan generated with detection information from 2004-05-06. The most
recent detection information is available at invcif.exe from
http://go.microsoft.com/fwlink/?LinkId=19074--

Any ideas on what I need to do to get this to work?

Thanks.

John
