Had to re-install NetStorage after server move to VM (the registry did not get kept, as I did NOT move the DOS partition)

No problem there, but I can not login to /oneNet/nsadmin or in iManager File Access (NetStorage) I have nothing under Authentication Domains & can NOT add anything (it just comes to the same empty screen)

Google helped with: Possible NetStorage Login Latency after Applying OES2 Updates

which leads to good TID 3374174 - How to recreate missing Xtier registry keys

which allows manual creation of the missing key(s), after which NS works again
