[Samba] "smbclient -L servername -N" not working

I would appreciate any ideas on how to correct the problem that we are  
having that is outlined below.  Thanks for your help.

I have been running samba for a long time.  Currently we are having  
problems with it filling up /var/log/messages with

Feb  7 10:45:02 servername smbd[2157]:   Can't become connected user!
Feb  7 10:45:02 servername smbd[2158]: [2008/02/07 10:45:02, 0] smbd/ 

In doing the list of checks on samba and nmbd, I find that only

smbclient -L servername -N
Anonymous login successful
Domain=[DEPT] OS=[Unix] Server=[Samba 3.0.25b-1.el4_6.4]
tree connect failed: NT_STATUS_LOGON_FAILURE

doesn't work.

smbclient -L servername -U username

works fine.

rpm -aq | grep samba

uname -r

Our guest account, chemug in samba, cannot log into the system.   
Regular accounts on samba are having no
problems connecting to and printing through our server.
