You should see a Linux based station as the IP address for the Linux
computer if you scan from the network.

The Windows 2000 Pro VM may be scannable (or possibly some services
on it could be if they are made publically accessible on the outside
network) depending on whether it is using a 'bridged', 'NATted' or
'host only' network connection.

1. Bridged.

If the Windows 2000 Pro VM has been given a public IP address on the
network (e.g. a separate IP # which is bridged by VMWARE) then the
Windows 2000 Pro virtual computer should also be scannable from the
network.  Note that the Linux IP address would be separate from the
Windows 2000 Pro IP address and they would appear to be two completely
different machines when scanned from the network.

2. NAT

If the Windows 2000 Pro virtual machine has been set up as with a NAT
(Network Address Translation) network configuration which just exists
inside VMWARE (and then shares the IP address of the host OS) any access
from the Windows 2000 Pro VM would have to go to the greater outside
network by having the private internal IP address (and in some cases port #)
translated use the IP address of the host OS (and possibly a new port #).

Incoming traffic is similarly translated by NAT mode.

For the most part the the Windows 2000 Pro computer would not be visible
nor scannable from the (outside) network.  However, if you were able to
expose a service port with a server listening to it running on the W2K
Pro VM to the outside world (via NAT and the host OS) then that particular
service could be scanned.  I've never played with the NAT functionality
within VMWARE so I don't know if it is possible to expose a server process
to the network outside of the host OS or if only client IP access from
within the VMWARE NAT environ is possible.

3. Host-only mode

In host only mode there is theoretically no direct network access from the
outside network, neither to nor from the VM (virtual machine, W2K Pro in
this case).  The VM is isolated and only connected to the host OS through
a fake private network.  It should not be possible to scan the VM from the
(outside) network at all.

If the VM can get to a proxy service running on the host OS it may be able
to access the outside network via proxy. And there are reverse proxies
(which work in the reverse direction) so services in the VM environment
could potentially be explicitly made available to the outside network (and
hence to scanning of the particular service).

Hello all,

question: if I scan a station that has Linux as host operating system and Windows 2000 Pro as guest operating system using VMWare software what will I see? A Linux based station or a Windows based station?

Thank you and good work to all.
