samba - Jul 2004 - XP SP1a can join domain but not log in.

I've posted this before but had to leave town and wasn't able to follow
up... I'm still having this problem.  Here is what is in the logs when I try
and log in.

[2004/07/14 07:58:02, 0] smbd/password.c:authorise_login(863)
  authorise_login: rejected invalid user nobody

Original Message:
Wondering if anyone can help.

Here is my situation, I have a RH 7.3 machine running a compiled from source
rpm version of samba 2.2.7.

We have been a win98se (which works great) shop for sometime but are
migrating to XP Pro machines slowly.

I can get the XP machine to join the domain (and the machine account is
created in both the /etc/passwd and /etc/samba/smbpasswd file) but when I
reboot and try and login as a user on the domain I get the following error:

"Windows cannot connect to the domain, either because the doamin controller
is down or otherwise unavailable, or becuase your computer account was not
found.  Please try again later. If this message continuses to appear,
contact your system administrator for assistance."

Now I can just log into the local machine and map a drive no problem and
i've done the sign or seal hack.

Anyone have anythoughts?

Thanks,
Brad
