[Samba] Reliable Samba just stopped mounting Windows machine
I have been mounting a Windows machine with no problems whatsoever for
the year. Suddenly this afternoon it won't mount any more. No recent
changes have been made on the machine. The only thing I've done
recently is load and get Thunderbird working. Most things are done as
user not root in KDE xterms.
My Linux machine is Slackware Linux 10.0.
There is an iptables firewall that allows tcp input on port 139 but not 445.
I have fsck checked all the filesystems with a Knoppix cdrom.
smbd and nmbd are running.
The Windows machine runs Windows 98SE
and is on the same local subnet as the Linux machine.
In fact they are next to each other on my desk.
The Windows machine can browse all usual shares on the Linux machine.
The drive is shared as C with full access, no password
and the Network settings allow share level access control with no pwd.
My smb.conf is attached.
What should I be looking at?
Any idea what went wrong with this previously super reliable system?
===========More details below:

When I run mount this is the result:

network.
# The following example restricts access to two C class networks and the
"loopback" interface.
