[Samba] upgrade from 2.2.x to 3.0.0

[Andrew Judge]

I upgraded (a side by side migration) from RH 7.3 to RH EN v.3 and one of
the packages was samba acting as a PDC.  Was working beautifully, but now
some XP machines don't see the new server at login.  Password are cached so
not a huge problem.  One machine didn't cache the password.  I deleted the
machine account from the samba PDC, put it into a workgroup.  I then tried
to add it to the domain and I get "can not find user" as root.  root is
there and valid.  When I use a bad password for root, it says that I am
using a bad password - so it sees the user?  Nothing unusual in the logs and
event viewer.

I migrated by:

1. copying passwd, shadow, group
2. copying smbpasswd
3. creating the ntadmin group
4. modifying the smb.conf file

my smb.conf (testparm)looks like

[root at fire2 profile]# testparm
