Hi, i have this problem: I have a Ubuntu server with Samba working as a PDC server for a windows domain. I have followed the tutorial: Samba tutorial for Ubuntu 5.10. All machines are Windows XP Professional. I have joined all users to Samba with no problems. The problem is when a user wants to access another machine in the domain, it asks for an account (user and password) for entering that machine. This happens with every machine and every user. Any help or possible correction will be aprecciated. Padmx Sorry for my english, I´m from Mexico.
