Hello John,
Thank you for your message.
I believe it's the B machine that is headless. In this case you could:
1. Build an MSI Host installer using the MSI Configurator. You can pre-configure the Host with your settings (e.g., Internet-ID, password, etc.) during this step.
2. Push-install it using standard MSI installation parameters. For example, from Computer A you can use a command like this (via PsExec or similar):
msiexec /i path\to\host.msi /qn
About MSI parameters.
If your pre-configured MSI was built with embedded settings, this method will install the Host on Computer B without requiring GUI access or interaction.
Hope that hepls.
