Hello all. I have a strange issue with my samba machine. I upgraded from 3.6.22 to 4.1.6, everything is looking good. wbinfo -u shows me all users, wbinfo -g list all groups, id user gives me all the info. I can browse the share without problems. I can delete files from the share, i can put files on the share BUT as soon as i open a file, or when i try to copy a file from the share to the windows machine i get error messages on the windows client. The error in Dutch is: Er is een probleem met het krijgen van toegang tot I:\data\filetocopy Zorg ervoor dat de computer verbonden is met het netwerk en probeer het opnieuw. In my best translation it is: There is a problem accessing the file I:\data\filetocopy Make sure your computer is connected to the network and try again. I have rebuild samba, i have removed all tdb files and joined the domain again, I also minimized the smb4.conf file but the problem stays. I see no core dumps or other errors in the log. Can someone help me with this. I am on FreeBSD 10-Stable regards Johan
