This is a bit strange. After months of successfully scanning subnets for unmanaged machines, UDD acts like there is nothing new out there. I have over 150 laptops that I deployed that simply will not show up. I run the scan using standard settings, applied against specific subnets. Lots of computers are found but not added so I end up with 1, maybe 2 new ones to send the agent out to. I know they are there!
We're running 9.02 (SP2).
To get around this issue, I grabbed the Advance Agent .msi and have created a GPO to push it out....that's not working either. No firewall turned on. No sign of the files ever making it to the workstation. Stumped on this one.....
