I'm new to the Linux OS, and thanks to the tutorial for setting up a Samba domain controller (running Ubuntu), I got a Windows XP Pro client computer to join a Samba domain, with roaming profiles. The same client computer is actually a dual-boot computer that also has Ubuntu. I would like to have the same Windows XP roaming profile functionality when users boot into Ubuntu Linux. There seems to be a lot of information on the net about getting Linux clients to join a Windows domain controller, but no information about joining a Samba domain controller. When I try to use instructions about getting a Linux client to join a Windows domain, I run into problems about a missing NTP time server on my Samba server. Should I try to install an NTP server on my Samba server? Thanks for any suggestions you have. Denny
