Hi all, since a few weeks we have a very strange behavior. It happens from time to time that some XP Clients are not closing the "filehandle" on the Samba Server. If I want to rename a file or see the permission of it, my XP Client stops responding. After some minutes or sometimes hours, the File will be accessible again. I can use smbstatus to see which client keeps the file open (smbstatus -L | grep filename). If I kill the process or reboot the Client which keeps the File open, I can rename the file again. This Error appears after the following changes: 1. Move the XP Clients to an ActiveDirectory Domain (w2k8) 2. Use new Network Switches And it appears on different Samba Servers (some authenticate to AD some to an old LDAP). Hopefully someone has an Idea what could be wrong......... I am using Debain Systems (one Ubuntu Server). Samba Version 3.0.24 and 3.4.7 (on the Ubuntu) This is my smb.conf: netbios name = storage2 workgroup = HURTSAPPL wins server = 192.168.105.50 server string = Storage Server 2 (%v) hosts allow = 192.168. security = domain encrypt passwords = yes password server = PDC socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 interfaces = 192.168.102.2/24 192.168.101.2/24 192.168.103.2/24 bind interfaces only = yes log level = 0 log file = /var/log/samba/log.%U max log size = 10000 null passwords = no hide unreadable = yes hide dot files = yes dos charset = 850 dos filemode = yes unix charset = ISO8859-1 domain master = no local master = no preferred master = yes os level = 2 load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes smb ports = 445 Regards, Stefan
