To add, getting LOADS of these in wireshark: 3975 70.694431 192.168.1.3 192.168.1.69 SMB Trans2 Response, QUERY_PATH_INFO, Error: STATUS_OBJECT_NAME_INVALID .69 being my workstation and 1.3 being the DC with the file share. I've also noticed the ntfs perms are way off, alot of files were copied over from DC to DC yesterday, there are duplicates of the same ACLs with with inherited / non inherited status. Looks like NTFS perms are to blame?
