Hello, I have following problem: We have to replace Windows 2003 domain controller with Windows 2008 . Previously used version of Samba don't work properly with Windows 2008 (security issues) therefore I upgraded one of file servers(FC8) to Samba 3.0.33 (Release 0.fc8). Result seemed to be ok until I realized that I can access shares only via hostname, for example: \\smb2.mydomain.net or just \\smb2, trying to reach it via IP is impossible. Result is: Windows cannot find \\IPADDRESS....blablabla I also deployed completely new machine (CentOS 5.5, Samba 3.0.33, release 3.28.el5) just to be sure that it is not because of bad upgrade process and result is the same. I need access to server just by IP as I have separated localizations(LAN's) where DNS is not always working as it should. Below my smb.conf file: [global] workgroup = MYDOMAIN realm = MYDOMAIN.NET server string = smb2 security = ADS log level = 3 log file = /var/log/samba/log.%m max log size = 50 idmap uid = 10000-20000 idmap gid = 10000-20000 winbind separator = + winbind enum users = Yes winbind enum groups = Yes [test1] comment = Test Dir RW All path = /Data/export/test1 read only = No [test2] comment = Some System Limited Access path = /Data/export/test2 valid users = %D+name.surname1, %D+name.surname2 read only = No Any help will do as this problem stops our domain migration. Thanks in advance. Dawid
