Hmmm, so Intel Device Spy doesn't find the DSM-320 but _does_ find the
WMC running (I don't remember if it see the DLink Media Server or not
- ie whether that server is actually UPnP AV compatible, or using some
other private protocol).

It really does sound like the DSM-320 has a funny IP address, or at
least one that is outside of what your router thinks is an "internal"
one, such that the traffic to/from the DSM-320 is not being passed to
other devices within your home network. Can you check that the network
settings on the DSM-320 look reasonable; that is that it has its
gateway device and DNS as your router (actually probably best if you
have it set for DHCP, then just confirm these numbers look
reasonable), and that your router's DHCP table sees it as having
leased an address successfully.

To summarise, and hopefully stir the interest of someone reading this
with more clues than me, I think this is what you have:

* DSM-320 and PC running Media Server software are on a home LAN
behind a router.
* Home network is in address range 192.168.*.* and both DSM-320 and PC
have an address correctly in that range (and correct subnet settings,
etc)
* DSM-320 does have Internet access via a router (was able to go to
DLink FTP server and update its firmware).
* the DSM-320 cannot "see" a computer on the LAN running media server
software - either Microsoft WMC _or_ DLink's own server software.
* The Intel "Device Spy for UPnP Technologies" application can see the
Microsoft WMC software, but CANNOT see the DSM-320.
* The DSM-320 has never worked with the intended server PC, either
before or after updating it to the 1.04 firmware.
* The firewall on the PC is disabled.

Gee, I really don't know. It sounds like you have a completely
"vanilla" connection scenario, but that the PC and DSM-320 are
"invisible" from eachother. I don't know if the DSM-320 responds to a
"ping", and can't test right now (it is running a Linux kernel
underneath, so it has to be a chance), you could try a ping or tracert
to it from the PC running the server software at the IP address it
says it has leased and see what happens.

Sorry, I'm pretty-much out of guesses from down here; hopefully
someone else can chime in with the magic answer if there isn't any
further help for you in what I've posted above...

What is the IP Address of your WMC?  What is the IP address of your Media
Lounge?  Both must be in the "private address range" or "Auto IP range" for
WMC to work.  Look for IP addresses like 192.168.*.* or 169.254.*.* (among
others).

Regards,

I found that the order that I turned on the devices matters with WMC. Turn
the DSM-320 on first, then start Windows and WMC. Then perform the Site
Survey under the Setup > Network. See if you find the server then.
