I have problem with mounting Windows network shares from my OS X 10.7.5 - it worked but it stopped and nothing helps and nothing in logs.

Here what I get when trying to mount it manually:

mount -t smbfs //10.0.0.7/d /tmp/test

When doing sniffing with tshark - no packet it sent through and I get immediately return from the command:

mount_smbfs: server connection failed: Unknown error: -1

Nothing in /var/log/syslog.log and /var/log/kern.log.

The Finder does not work either - it throws an error that something is wrong (in czech thus I'm not sending the message here).

I just cannot connect to any network shares.

In virtual Windows 7 in Parallels Desktop I can connect successfully, but not within the network share (so the Win7 is behind OS X NAT) but only with its own IP address.

The Windows server share is on the same network segment connected through switch.

Any advice how to debug and what can be wrong? I spent hours to find solution on Google and here but no-one with this kind of problem and I do not know how to further debug it since there is no meaningful log / trace etc.

I can ping 10.0.0.7 and I can connect to FTP server on 10.0.0.7 - the Windows machine (XP) has firewall completely turned off. The problem is that with tshark, I'm not seeing any packet sending to 10.0.0.7 so it's not even trying to reach the server.
