[Samba] Users can't login any more

[Gaiseric Vandal]

Samba 3.5.3 should recent enough to work properly.

You should probably trouble shoot your Windows 98 and XP machines 
separately.

Do you have any real XP machines?  Were you XP machines working prior to 
this problem?

Do you get the errors in the smbd log everytime you restart samba?  Have 
you restarted samba recently?

Does "smbclient" work if you specify a user name (Administrator or 
another user?)

Do the accounts look ok in "pdbedit -Lv" ?
