nmbd failed - can not see nas4free server in win7

[qaqz111]

Hello to everyone! There's a problem on my nas4free server bothered me for quite a while.

The nmbd failed during smb start up progress, I can't see nas4free server in win7 explore. The smbd is started successfully, so I can use '\\192.168.101.100\xxx' to access files on nas4free server while '\\nas4free\xxx' got an error in win7.

There are only 3 machines on LAN, the nas4free server(also the xp machine) with ip 192.168.101.100, the win7 machine with ip 192.168.101.102, the router as gateway with ip 192.168.101.1.

But I can see xp's, acturely it's the same machine, the nas4free is installed on a usbkey and I use it to boot xp machine. I can access xp's share in win7 use both '\\xpmachine\xxx' and ip address. So this definitely is not the win7 side problem.

The xp also nas4free server machine has 2 network interfaces installed on the system, which were recognized as sk0 and vr0, but only sk0 is connected to the router and is configured with ip 192.168.101.100, vr0 is not connected.

I've searched through the faq and forum, it seems there is no similar issue before.
I've read these posts but problem not solved:
NAS server not showing up in File Explorer of Windows 8
'net use' fails with netbios, succeeds with IP
Win7 cannot see NT1 CIFS share
only working on some windows

Here's the log of nmbd(please note underlined messages):

Thanks!

Anyone up?

[rostreich]

Quick possible resolution:
Backup config file
Kill data on your usb stick
Install fresh .636 on stick
import datadisks
configure cifs with shares
fire cifs up

added interface sk0

what chipset is this? and what NIC is vr0?
you sure that nothing is messed up with opt1 etc.?

[qaqz111]

I installed .636 right after it came out(fresh), the problem is still there.

sk0 is an onboard chip, 3Com 3C940 Gigabit LOM.
vr0 is a PCI card that plugged onto mainboard - D-Link DFE-530TX Fast Ethernet Adapter (Rev B).

OPT1 is set to none.

[rostreich]

switch off sk0 in BIOS. reset n4f to standard settings and try to use vr0.

if that works, you have a clue where to dig deeper.

[qaqz111]

Yes, maybe I should try another card.

I've just removed vr0 from mainboard，and flushed n4f in usb stick，the problem is still there.

Thanks. I'll check it out.
