Hi! We have a windows NT PC as our PDC. Currently planning on migrating to UNIX / Linux. For testing we have put up a Linux Red Hat 7.2 System, with Samba 2.2.5, which I configured on it. Now the problem arises when the users for Linux want to access to Windows NT computer. If they are not users on the NT system they are unable to do so. I learnt that we can make the Samba machine join the Windows Domain by making use of the commands: smbpasswd -j NTDOM -r NTDOMPDC where the Domain name is NTDOm and the name of the domain controller is NTDOMPDC. Will this work? I just want to make sure before embarking on this issue. Thanx for the help. Gagneet PS: Requires a machine account on PDC SAM database and the changes to the smb.conf file.. 'smb.conf' file: workgroup = NTDOM security = domain password server = NTDOMPDC
