[Samba] Domain logins not working

[Gary Dale]

I'm trying to set up a new server to replace my previous domain
controller/file&print server on my home network. My old server was
running Debian/Etch on a 32bit sempron system with two HDs. The new one
is running an old 64bit single-core processor and 3 HDs configured into
multiple RAID  1 and 5 arrays (/boot as RAID 1 and /, /home, swap and a
/backup directory as RAID 5).  The new server is running Debian/Etch+1/2.

Samba was installed by default since I specified the new server as a
file & print server.  I rsync'ed the old /home to the new one to get the
files across. Then  I used SWAT to make my old server a member server
and the new one a domain controller. Since I only had a few accounts I
set them up manually on the new machine, taking care to ensure that the
new Unix ids matched the old ones.

File sharing is working well after I remapped the drives on a running
XP/Pro workstation. However, I can't get logins to work. I've set up
machine accounts for each XP/Pro workstation and used SWAT to create the
new Samba accounts and enable them (with the same password as before)
but XP/Pro refuses to allow the logins. I also tried mapping a share on
the old server to a directory on the new and I get the same problem -
it's having problems finding a DC.

Here's my smb.conf (minus most of the shares), if that helps (ps, I will
set the log level higher as part of my debugging so don't suggest I do
that. However, any suggestions on what may be going wrong are welcome.
:)  ):
