Win XP's Universal Plug and Play Device Host service starts and then stops immediately

It's the wierdest thing, I noticed today that my UPNPhost service is
no
longer working on two of my XP machines. I noticed it on my desktop
first, so I went to my laptop to compare, and found out that it's not
working there either! I've checked through a number of webpages and
none
of them have had the solution for me yet.

So I'll go through what I've already done.

(1) The upnphost service was not working, so I tried to re-enable it
in
the services manager. I made sure that it's dependent services were
also
running (and set to automatic), SSDP and HTTP. The following message
popped-up after the attempted startup:

"The Universal Plug and Play Device Host service on local computer
started and then stopped. Some services stop automatically if they
have
no work to do, for example, the Performance Logs and Alerts service."

(2) I then went to see if the XP firewall was blocking the UPnP
Framework. It wasn't, it's listed within its exceptions list.

(3) Another article suggested that the problem might lie in the
registry, it suggested that I go into regedit and make sure that the
"Local Service" user account have full control permissions over the
following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UPnP Device Host

The permissions were already set properly. This was suggested in the
following article:

(4) I then went and tried to uninstall and reinstall the UPNP services
in Add/Remove Programs. This made no difference.

(5) I got stumped, and came here for help. :-)

As the description said, it will stop if it's not needed, is there some
reason why you think you need to have it running constantly?

Well, because it used to run constantly, and recently I started having
some random port-forwarding problems on some applications that use
UPNP. I have a UPNP diagnostic program called UPNPTest which I use to
troubleshoot UPNP problems, and it mentioned that this service was not
running.

So you are saying that this service isn't needed by applications that
use UPNP? What sort of things are considered UPNP devices? Would
routers be such?

Hi
Yeah, many Routers have UPnP capacity. Usually the Default is Off (it is
considered a Risk to leave it On).
If you need the UPnP, log to the Router and switch it On.

Routers that support uPnP would be such, if - as has been said - that function
is enabled at the router.

fwiw, I don't allow uPnP at my router for security reasons, preferring to
manually configure any required port-forwarding, and the uPnP service on each
of the many XP systems on the lan eventually stop after boot-up, which would
confirm what Jack has said.

Perhaps you've cooked yet another network appliance? ;-)

Hi
You probably have No UPnP Device on your Network, so it stops.
