Hi, I am have SAMBA configured on Linux, Solaris & HP UX machine. All version are lower than 3.4.7. I am able to access SAMBA Shares from Windows XP, Windows NT / 2003 Server. Recently we added Windows 7 and Windows 2008 Std Edition as client but I am unable to access Samba Shares from Windows 2008 system. After changed following registry in Windows 7 Now i am able to access Samba Shares. HKLM\System\CurrentControlSet\Control\Lsa\LmCompatibilityLevel But Problem is still with Windows 2008. I have gone through no of postings and made changes in security option but no luck. Any idea what how to resolve this issue. Following Global Parameters are set. workgroup = WG01 realm = localdomain.com server string = File server%v on (%L) netbios name = <localhost> security = SERVER encrypt passwords = Yes update encrypted = Yes password server = 192.168.x.x log level = 3 log file = /var/log/samba/samba.log.%m.%R name resolve order = wins dns bcast hosts wins server = 192.168.x.x case sensitive = Yes Thanks in advance.
