Hello all, we use Samba to serve about 20 DOS/WfW/Win95 machines in 'security=share' mode. We use unix accounts as password validation, so I _know_ our Samba does not accept encrypted passwords. On Thursday, we added a NT4/SP3 box. I expected it not to logon before we made the plain-text password registry patch, but it did! It's a new NT installation (on a new AMD K6 box), so I don't expect the registry to be already pached. Does NT use password encryption only for domain logons and plain-text passwords for 'logons to workgroups'? Ludolf
