I set up a ubuntu server (running ubuntu desktop) connected to about 15 pcs using samba. All going good for a month now. I never set up any users or groups (not sure how).
Today one of my colleague said he needs to make one of the pc's not accessible to the server.
Can anyone please help on how to do this?
Also I like to know how to setup users and groups too (im assuming this might be necessary to solve my question too?)
Thanks for your help
