[Samba] Unable to join Windows2003 machine to Samba domain

[Don Watson]

Hi all,

Attempting to join Windows2003 machine to Samba domain results in "The 
specified domain either does not exist or could not be contacted".  No 
messages show up in log.smbd on the PDC server following the attempt (I have 
log level set to 5).

I can however ping the PDC machine, and can see it by entering its hostname in 
"Start->Run".  This causes messages to show up in log.smbd on the PDC server.

I recently installed a series of linux security fixes; I do not know the 
details since I installed automatically using online_update.  Thinking this 
might be the source of the problem I have turned off the firewall, but still 
have the problem.

I see lots of this problem in Google, but none of the suggestions have helped.

Thanks for any suggestions anyone can provide.
