Hi,
I tried this in our environment 9.6 and ist working fine. The client with the remote console is a Windows 8.1 x64, so this should be a special problem at your side and not a global bug.
Did you try it with the same credentials, maybe ist a permission issue? You said the SCN file is created under coreservername\ldlogon, are you sure it's not in coreservername\ldscan? Check the eventlog on the core if there are errors or warnings regarding the inventory service at the time you try to create the bare metal server. Are there any entries?
Kind regards
Christian
