I have an existing Vista client that has the SCCM client installed. I would like to use SCCM to capture an Image of this machine without having to use Boot media. In other words, I want to not have to touch the client. I have set up a custom task sequence of a command line that reads c:\windows\system32\sysprep\sysprep /oobe /generalize /reboot /unattend:c:\unattend, and included an Image capture step. When I advertise the task sequence to a collection which included just my one machine, nothing happens. What am I missing?
