As long as the agent package (framepkg.exe) is taken from your ePO server, then all you have to do is install it - this package knows where the ePO server is and the machine will register with ePO automatically.
With regard to installing EEPC, please see KB71822 - hopefully that will help
thank you for the information. I need as well as the information how to include the users to the machine in ePO together with the installation of eepc. We want to automatize the installation including registering the users to the machines.
According to my colleagues, this is not possible, I'm afraid - the machine needs to talk to ePO before the users can be assigned.
I'm not sure if this helps depending on what you're trying to acheive. But the EEPC product policy setting “Add local domain users (and tag with 'EE:ALDU')” could help you automatically assign logged on/cached users to pre-boot, but if you need more control of adding users it might not be feasible.
