That suggests either a configuration difference with some of the win 7
machines or a difference with some of the AD accounts for the machines.
On the NAS, does the "getent passwd" command display user and machine
accounts? Is it may be showing only some machine accounts and not
others? It might be possible that samba has been unable to account an
idmap entry for newer machines. All though I would think this would
affect authentication issues, not connection issues. I have found
idmapping to be one of the less reliable functions in samba.
Are all the Win 7 machines configured with identical network settings
(apart from the IP address itself of course.) this should be the case if
you use DHCP.
Are their any security settings on the problem Win 7 machines that are
different? If you use gpedit.msc -> computer -> security settings ,
you may want to review things like NTLMv2 settings. Are all the
machine accounts in the same AD container ?
If this is all AD, then you should not need to use WINS. Although it may
also help resolve confusion about which machine is the local master
browser. Which shouldn't really matter either. I use samba 3.x as a
non-AD PDC so the WINS and browser stuff is more important.
Is the Microsoft server is the AD PDC it may expect to be the local
master browser. I think there can only be one local master browser per
subnet. And if you look thru the nmbd logs (?) on the NAS as well as
the logs on the Win 2008 server . you may see results of a browser
election.
the "testparm -v" will show you all the config settings, including those
set by default even if not explicitly set in smb.conf

Hi,
all XP clients work fine. As do most win 7 clients. Just a handful of
win7 clients have this issue.
We only have one Microsoft server: 2008 R2, it does not have the WINS
server feature installed.
The qnap box is called saturn and is a member of the domain
telnet saturn 139
results in blank screen, blinking cursor so port open I guess.
NAS uses our Microsoft server for it's DNS and registers itself in DNS
Also on the NAS I have:
Enable WINS server NOT checked
Local master browser checked
Allow only NTLMv2 authentication NOT checked
DNS has a reverse lookup zone with a PTR record for client

(I skipped vista.)
Can you check in smb.conf
- is the server a member server, AD member server, standalone
server, or domain controller.
- Are ports explicitly defined
- how is name resolution configured?
- is NTLMv2 required (I couldn't get NTLMv2 support working.)
Domain membership shouldn't matter at this point since you aren't
even getting to the authentication phase.
Can you telnet port 139 to make sure it is open?
Do you have a WINS server defined? If so make sure client and
NAS are using the same WINS server. Is your NAS configured to
use a DNS server? Do you have a reverse lookup zone defined in
DNS? the NAS maybe trying to do a reverse lookup on the IP of
the client. There doesn't need to be a PTR entry for the client
but you are least want the zone. If DNS tries to lookup an IP
and gets an immediate "host not found" that is OK. If it times
out because it can't even locate a DNS server then that could
cause problems for other services dependent on DNS.

hope that is correct ?
Yes I can edit the config file on the NAS
Looking at the network packets all communication to NAS seems
to be on port
microsoft-ds (445)
I can't see any traffic on ports 137/138/139
If i use the IP I get exactly the same error :(

I think the "Error was Transport endpoint is not

sometimes misleading. Do you have any control over the
samba config
(smb.conf) on the NAS ? On regular samba installs,
changing the default
port settings can cause more problems.
Windows 7 will try to connect on port 445 (SMB or CIFS
over tcp/ip), and
will then reconnect to ports 137/138/139 (SMB over netbios
over tcp/ip)
since samba 3.x doesn't handle the newer SMB-over-tcp/ip.
Disabling
445 on the server seems to cause more problems than it solves.
Are you able to connect via IP ? e.g net use
\\qnap_ip\share ?
I had problems in the past when I disabled port 445 on
samba servers.
Remote users (no netbios broadcasts permitted) could
connect via IP but
not via name. For the name only connections, packet
monitoring would
show packets getting thru the the server but the exchange
between client
and server not being completed. For clients connecting
via IP, the client
would send packets to server, server respond, and then
clients responded.

I've started reading the o'reilly samba book but
finding it hard going.
Anyway I'm trying to map a network drive from a
windows 7 pro client to a
QNAP NAS with the command:
net use s: \\qnap\share
I've posted on several forums and got good advice but
the problem remains.

I've also installed MS network monitor on two clients
and did a capture
whilst running the command
net use s:\ \\saturn\staff
I've posted three screenshots here:
https://plus.google.com/**photos/108734482620454690509/**
albums/5875135861918839393?**authkey=CJ3lwKu2xJqMyQE<https://plus.google.com/photos/108734482620454690509/albums/5875135861918839393?authkey=CJ3lwKu2xJqMyQE>
Basically, Worked.png shows the SMB frames on a PC
where the net use
command worked
and Failed.png shows the SMB frames on a PC where the
net use command did
not work
It looks to me like the first 6 SMB frames are
identical. Then things
start
to change
On the working client we continue with frame 10113
which is a
Dfsc: Get DFS Referral Request
but the failing client continues with some TCP frames (see
tcp-frames154-157.png) 154 to 157
before it seems to start the negotiation again at
frame 158
Not sure how to troubleshoot this further so any
advice welcome.
Thanks
Ed
