First of all, i wanna quickly say, that i have no experience with linux or their cmds so it is okay to tell me stuff like i am stupid. cause i am.

So, i have a problem with my linux project i am currently working on.

At the moment, i have a pc with ubuntu linux server 20.04, a pc with ubuntu desktop and a windows 10, and i need to sambashare from the server to the windows and ubuntu machines, so each user has their designated folders with the right restrictions so only the right people can look in which folder.

I have indubitably done so with the windows pc, since all users have their folders, and the admins can see all folders, as specified in my project. The only problem is that i can't get access to the ubuntu server on the ubuntu desktop.

i've tried basically everything i could think of. not sure how to get on.

and yet, when i restart the nmbd and smbd, restart the client, i can't access the server to see the folders, all i get is:

so far i haven't been able to find someone with a solution to my problem, so any of you guys have an idea?

also forgot to include this, for those who wanted to see it, but i have set up the /etc/samba/smb.conf and for some of the users, it is basically this:
