Hi, I've got samba 2.2.7 running as a PDC, with XP and 98 machines on the domain. If I set up a share on a PC, with permission restricted to a certain user account, e.g. "John" then log on to the domain on another PC as user "John", I can't access it; if the share's on an XP machine, I get "The trust relationship between this workstation and the primary domain failed", and if the share's on a 98 machine I get "there are no logon servers available to service the request". If, however, I log on to the domain as "Stu", then map a network drive, connecting as "John", it works fine. Any ideas??? All XP machines have had the signorseal registry hack applied... Thanks, Stu
