We join the domain during the setup as well ... but we are not facing that issue.
You are using the relevant entries in the unattend.xml for that ?
In step 14 the postinstall script runs, which in addition installs the agent.
When it hangs is the agent already there ? Can you telnet to 4750 for example ?
Is there anything else that you run as part of the postinstall script that might be causing this ?
How are things progressing with this one?
Been working on other things. But again, I'm pretty sure this is a GPO. We are probably just going to move the domain join to a script in the PPBJ.
