samba - Jun 2010 - How can Samba both work, and, suddenly stop working, simultaneously?

Samba, (smbd version 3.0.20) has been working splendidly on my machine
for more than four years. It has run without a hitch. And then
suddenly, today, it has stopped working. I haven't changed anything, I
haven't installed anything on the server and I haven't removed
anything. So I'm at a loss to know what's wrong with it.

I can only interact with the server from the local command line. (I
haven't altered the allow hosts in the config file. I haven't changed
anything) I used to be able to reach it from all the machines on my
network with windows \\10.10.10.1
ERROR: the network path \\10.10.10.1 was not found

The machines can all reach each other remotely, (it's not a connection
or cabling issue. And I can't connect to the samba server from any of
my clients since this morning) But I can access all the other servers
running on the same host.)

The samba server is running
root     243  0.0  1.9  4784 2356  ??  Is    9:24PM   0:00.02 /usr/
local/samba/sbin/smbd -D
root     245  0.0  1.9  4784 2356  ??  I     9:24PM   0:00.00 /usr/
local/samba/sbin/smbd -D
root     246  0.0  1.3  3104 1624  ??  Ss    9:24PM   0:00.05 /usr/
local/samba/sbin/nmbd -D

smbclient -L SambaServer1 -U%
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.0.20]

--then it lists my shares-----------
netstat -an|grep 137
udp4       0      0  192.168.1.22.137       *.*
udp4       0      0  *.137                  *.*
netstat -an|grep 445
tcp4       0      0  *.445                  *.*
LISTEN

Any thoughts would be appreciated,

A few more information might help getting the whole picture. For
instance, the ouput of "testparm -s"  (better that just sending out
smb.conf as it skips settings that have their default value).

Also, you should check what's appearing in samba log files when you're
trying to connect to the server.

As of now, it is more sounding like you have an external cause and
your problem looks like a browsing problem. Didn't one of the windows
machines steal the samba server IP address?

testparm -s

Load smb config files from /usr/local/samba/lib/smb.conf
Processing section "[tmp]"
Loaded services file OK.
[global]
        workgroup = WORKGROUP
        server string =  Samba Server
        security = SHARE
        log file = /usr/local/samba/var/log.%m

[tmp]
        comment = Temporary data On Samba Server
        path = /tmp
        read only = No
        guest ok = Yes



===========================Thanks for getting back to me guys. No, it's not
an ipaddress conflict
issue. I can ssh onto the server, I can access the server on port 80, etc.
It's not a cabling issue. Samba has just stopped exporting its file systems.
It's running on the server itself and I can access the share(s) but only
locally. I can't understand it. I have no access/deny restrictions in the
config. (You can see the config above.)
