That's how it looks on my debian box. My VMware is running on RedHat though,
so there may be minor differences. In any case, your networking appears to
be working (other LAN PC's can see the host) right? If so, you're OK there.

Go into the configuration editor for the virtual machine and check the
settings for the Ethernet interfaces. If there's only one, it should be set
to bridged. If it is, there's nothing more to do. If it's set to "host
only", just change it.

OK, so eth0 at is the interface that connects to
your LAN PCs...

It looks like your networking is all OK. A handful of questions:

1. Have you verified that you can ping from PCs on your LAN to your Linux
server? Are basic network services OK between the eth0 LAN and physical
machines (i.e. ping, telnet from desktop to server)? An obvious question,
but I want to make sure we're on track here.

2. What IP address did you chose for the guest VM? It should be on the same
subnet as eth0, but a different IP. Something like 208.46.58.xx where 'xx'
is a *unique* *unused* address on the subnet. Make sure it's an address
you're allowed to use and different from the Linux box itself!

3. Assumine you can ping between physical desktops and the server, can you
ping between physical desktops and the IP issued to the virtual machine
(guest)? If so, it's a browsing issue. Try doing a "Start->Run->\\funkmotor"
or "Start->Run->" from a physical PC and see if that opens the
server browse list for you. If so, it's DEFINITELY a browsing issue and
networking is working.

Mine's set to:

        interfaces =
        bind interfaces only = No

I would think the defaults would be fine, but you might try making this
change at least until everything's working.

If you can ping between physical PCs and the virtual machine, then it's
likely a browsing issue. It's possible one of the desktops is becoming the
browse master -- or perhaps an NT server? ASSUMING THERE IS NOT AN NT SERVER
that you need in control of things, you might try:

    os level = 33
    preferred master = yes

Also make sure that the physical desktops, Samba server and virtual PC are
all in the same workgroup.

If none of this works, you might try 'testparm | more' to make sure your
smb.conf is being parsed as you expected. Any "hosts allow" statements and
such can throw a wrench in the works!

Good luck!
