Hello Guy's it's the newbie again. So I managed to get the samba server running with the following configuration mentioned below. I have created a computer account on the samba server. When I want to join the XP client, I use the specified computer name and the domain name. When I click OK windows prompts me for the username and I use the user ROOT and the password. After a wile I get the error message 'INVALID PROCEDURE CALL" on the XP client and the computer is not joint to the domain. I need to get this working for a class exam project. Thanks for helping me out, again.
