Ok so I’ve fixed it, appears to have been an issue with the tool having come from my backup rather than installed directly.
couldn’t uninstall due to “missing shared content” so i deleted the file and verified integrity so it downloaded them - everything is now running perfectly, tried a few different games and they are working great.
cheers for all the help!
My understanding is that there are modules you can install to AD join a linux machine, i don’t know much about it unfortunatly because it’s not something i’ve ever had to do. I’m also unclear whether there is a different process per distro type.
I would speak to your company IT about it tbh.
