Hello, we struggeled now for several months but we couldn't manage to get this scenario working: Client: Windows7 Server: Samba 3.3.8. (RHEL 5.5) connected to Active Directory via Winbind Something seems to be wrong with the opLocks: as soon as we try to make any Samba share offline available, it fails. Client error: process cannot access the file because it is being used by another process Server error: oplock break failed for file ... As far as I understand this, oplocks are enabled by default on Vista or Win7 clients. On the server we enabled oplocks in smb.conf oplocks = yes level2 oplocks = yes kernel oplocks = no Does anyone use (Samba-) offline folder on win7 clients without any errors ? best regards
