Hmm interesting. Is the server log in question the server.log found under programdata\nomachine\var\log\? If it is, the log does update, but I can only view it using notepad++ opened in admin mode. If I make a connection, notepad++ will notify me the file updated.
This really does seem like some permission issue and almost like the nx account lacks something. Is there documentation on how to install nomachine on Windows Server and what permissions the nx account needs as well as any policies needing to be set?
The AD and group policy I’m using are the same for what I had configured between v8 and v9, v9 just seems to be particular for some reason
