You might try installing the Directory Services Client on those machines to
see if it helps, possibly trying one machine first which will allow W98 to
use NTLMv2 which may help depending on Domain Controller Security Policy. I
understand that there is also an updated version available from MS. You may
also want to raise your lockout threshold to at least ten which still should
be plenty adequate to prevent brute force type attacks unless you allow very
weak passwords. Supposedly in certain situations one bad logon attempt will
generate numerous failed logon attempts in the security log. Also read
through KB 823659 which lists problems that may arise with configuration of
certain security options [anonymous restrictions, smb signing, and lan
manager authentication level in particular] and user rights assignments that
may cause logon, password change problems, etc. --- Steve
