You can fix this by using the full (dotted) name of the domain, not the old
style NT name.
So, join samdom.example.com instead of DOMAIN.
Then it will work, at least for Windows7.
Today I noticed something strange. While it works OK for Windows 7, for
Windows XP it
only works when a computer account already exists in the AD.
I migrated to Samba by joining as an additional DC and then demoting the Windows
DC.
While the Windows DC was still running, I could join XP workstations to the
domain under
the old-style plain name. Computer account was created and domain joined.
When the Windows DC was shut down, I tried Windows 7 and it did not work, but
after
changing plain name to dotted name, it works OK. But with Windows XP it does
not work
with either the old-style or dotted domain name.
However, when I first create a computer account in the AD and then let the XP
system
join (as part of an unattended install) it works OK.
What can be the problem?
