[Samba] Samba 3.0.2a + Win2K clients: unreliable share access

After upgrading from 3.0.1 to 3.0.2a, accessing a shared folder has become unreliable: after being able to access my shares for some time I get an error message "No domain contoller was available" (actually, I'm paraphrasing that one, I unfortunately did not record it verbatim).  Host linux log contains the following error message for each access:

Mar  5 20:07:08 sharesmb01 smbd[4691]: [2004/03/05 20:07:08, 0] auth/auth_winbind.c: check_winbind_security(122)
Mar  5 20:07:08 sharesmb01 smbd[4691]:   check_winbind_security: ERROR!  my_private_data == NULL!

Googling the error message just led me to the source file for auth_winbind.c  

Any ideas for where I might try to find more info troubleshooting this?
