When you need to join a machine to the Active Directory It is a pretty straight forward task using either the User Interface or the PowerShell cmdlet available for that usage.However in some situation you don't have network connectivity and need to rely on Offline Domain Join, using the Djoin.exe tool. Typically you use djoin in two phases. First you generates a provisioning file that you drop on a newly deployed machine. In the second phase you run djoin with the file as a parameter and the machine is joined to the domain without connection to the domain controller.
My problem
Using that same method, I recently had a tricky problem to solve. The environment where I was performing this was very locked down, not allowing me to copy files to the new provisioned machine.
Fortunately the system handling the deployment could perform action on other systems and gather data. I could rely on something like System Center Orchestrator (or SMA) and get the content of the Blob file over HTTP/HTTPS by invoking a runbook.
Recreating the djoin file with the content was a bit trickier. Djoin is really picky on how the file is created. (see here and here for more information)
