Windows 7: No network access to Samba

I have a major problem. My Windows 7 RC Build 7100 can't suddenly connect to my linux server via Samba at all. It's been running for month doing just fine.

It's a wired connection. I can logon via SSH, browse public web folders, and ping host <-> client, both IP address and netbios name. However Samba is dead silent when trying to map a share.

I have checked the LAN configuration + Local Security Policy. Turning off the Windows firewall doesn't do a thing either.

When checking network, "net view \\192.168.0.2", it returns "System error 53 has occurred. The network path was not found."

Googling the above message mentions a "DNS problem", but I don't have a clue what to do next.

Running command "nbtstat -A <ip address>" on Windows client lists the samba server just fine. I can logon Windows account using smbclient from Linux host. Logging on a Samba share from Linux host works also.

Apparently there seems to be something on Windows 7 blocking any communication to Samba. I have checked the Samba log files, and everything seems OK. Though no trace of any logon or communication from client.

For testing purpose I've created a test share now with anonymous logon, to no avail

Any hints much appreciated.

Hi Jong,

Have you tried rebooting or installed any new AV software?

Yes, my Linux server is turned on only when I'm using it. On my daily hunt for a solution, it gets rebooted quite often

I have MS Security Essentials, and standard Windows Firewall on Windows client. Both have been disabled when testing the network.

There's no firewall installed on my Linux server, or other similarly software.

A question;
If the network is working properly, should I be able to ping computer name of Windows client from Linux host?

If yes, I cannot. Vice versa works OK though.

Hooray! I've solved my problem

My solution: disable IPv6 on WAN card, disable IPv6 component/tunnels. IPv6 was already disabled on my LAN card, but for some reason the tunnels blocked all access to Samba shares.
