[Samba] util_sock.c error connecting

[Alexander Lazarevich]

Samba 3.0.21c on RHEL4-AS x64.

Everything is working fine, but I'd like to find out what this error 
message in the samba logs is, and why it keeps happening:

[2006/03/20 13:25:06, 2] lib/util_sock.c:open_socket_out(907)
   error connecting to xxx.xxx.xxx.xxx:445 (Connection refused)
[2006/03/20 13:25:07, 2] lib/util_sock.c:open_socket_out(907)
   error connecting to xxx.xxx.xxx.xxx:445 (Connection refused)
[2006/03/20 13:25:07, 2] lib/access.c:check_access(324)
   Allowed connection from xxx.xxx.xxx.xxx (xxx.xxx.xxx.xxx)

Our samba authenticates to a windows NT4 domain controller, here are the 
lines in the smb.conf:

[global]
    server string = Main File Server
    wins server = xxx.xxx.xxx.xxx
    domain master = no
    preferred master = no
    netbios name = xxx-xxx
    load printers = no
    password level = 8
    security = server
    password server = xxx.xxx.xxx.xxx
    workgroup = xxxxxxxx
    encrypt passwords = yes
    large readwrite = no
    log level = 2
    max log size = 0
    socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE

The error happens 100% when anyone connects to a samba share for the first 
time. It seems like the windows domain controller refuses the first 2 auth 
request by samba, but then accepts the 3rd. Like I said, everything works, 
and authing with samba takes a fraction of a second. But I'd like to get 
rid of these errors if possible.

Any ideas?

Thanks,

Alex
