Samba as PDC denying access to W95 workstations

[Rob Ramsey]

We have a client where we setup a Redhat 6.1 box with Samba 2.0.5a (I
believe) acting as a NT PDC.  It has been working fine for the past 2 weeks
until today.  Now whenever users attempt to log on they get a "The domain
password you supplied is not correct or access to your logon server has been
denied."  Users can ping the samba server and telnet to it and logon to a
shell account.  Running a smbclient command from the server connects a user
without any problem. They just cant logon via a windows networking logon
anymore.   I installed a newer version of samba (2.0.6) and it is still
exhibiting the same problem.  Anyone have any ideas?  Copies of the log.smb
and log.nmb follow.  The broken pipe errors appear to start at the time they
first noticed the problem.

Thank you,
