[Samba] Connection by peers

[Elena_Sobol at atlantm.com]

Our Samba work very bad!
My some users can't save changers in Exel and Word files.
We have file-server ( Linux RH7.3, kernel 2.4.18, Samba-2.2.7a-1)
We local network consists of 500 computers with NT Domain Controller
(Win98,Win2000,WinXP,Microsoft Office 2000).
The user opens a file, he changes it and sometimes can save a file, and
sometimes no. Why?


My smb.conf

[Global]
        workgroup = WORKGROUP
        server string = "Samba server"
        netbios name = Samba
        os level = 32
        preferred master = no
        local master = no
        domain master = no
        security = domain
        password server = *
        wins support = no
        wins server = IP-adress
        name resolve order = wins bcast
        kernel oplocks = yes
        oplocks = no
        level2 oplocks = no
        encrypt passwords = yes
        nt acl support = yes
        nt pipe support = yes
        nt smb support = yes
        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=8192
SO_SNDBUF=8192
