Windows 2003 R2 server, Windows XP Pro workstations, Zenworks 10.1.3

I have been able to install the zen agent manually on 2 test workstations: with those 2 test computers I've been able to run an inventory scan, remote in and install/launch a bundle. With 150 discovered devices I'm unable to use the deployment task to install the agent. I have tried several different computers but I get an "error" under the deployment tasks.

What logs should I be looking at to help solve the problem? The zcc.log notes states : 1 of 1 deployment tasks successfully launched. But nothing ever happens on the target computer. I can ping from both workstation and server.
