samba - Feb 2003 - Users/Machines Unable to Logon to Samba PDC

I have Samba 2.2.7 running on RedHat Linux 7.3 (kernel 2.4.18)...  the system
has been running just fine since the initial install four plus months ago.  All
of a sudden, starting this mid-morning, users are unable to logon to their
Windows 2000 machines.  They receive the following message:

"The system cannot log you on to this domain because the system's
computer account in its primary domain is missing or the password on that
account is incorrect."

These same users were able to logon just fine yesterday...  and some were able
to logon just fine this morning...  but now nobody can logon.

Thinking that the computer account had gone bad for some reason, I changed the
workstation from being a member of a domain to a member of a workgroup, then I
deleted the account from Samba (using "smbpasswd -x computer$"), then
from Linux (using "userdel computer$").  I then had the computer join
the domain, and was welcomed to the domain.  After reboot, the same error
message.

If I logon locally to the computer, I am able to map drives (using "net use
x: \\server\share /user:username password).  I am also able to perform a
"net use" on the server.

What can I do and/or test to further determine what the problem is?

Never mind...  I found the problem.  Actually, I caused the problem.

I was removing some obsolete user IDs when I removed the "guest"
account.
Not knowing how closely tied it was to Samba.  Once the ID was
re-established, users (machines) were once again able to logon.

So, as an FYI...  the guest account is very important for machines to be
able to authenticate to a Samba PDC server.
