Hi, Windows binds user profile and SID in registry: HLKM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList\ I replaced old sid with new samba sid. It worked. After joining new domain, user got back his old profile. But if I look in "System properties" to the "Profile list", profile owners name is "account unknown". Where is the second place (for that list), where the old SID resides? anyone know? - Rauno Tuul -
