Universal Plug n Play or UPnP

[Guest]

I became aware that UPnP, not to be confused with "Plug N Play", by default
is enabled on Windows XP systems and should be disabled. How and where do I
check to see the current state of my systems UPnP services?

Look at the configuration for the SSDP discovery service and the Universal
plug and play device host services. Set them to disabled and stop the
service if you do not need them. You can use services.msc to see/manage the
configuration of services and services can also be managed via Group Policy
computer configuration in an AD domain. --- Steve

Hi Steven,

UPnP was not started but SSDP Discovery Service was started so I stopped
that service. If I may ask you a question, do I need either of these
services running if I want to run a home network or if I want to use VOIP?

 

[Guest]

Actually, what is the current thinking on disabling uPnP? Steve Gibson
(www.grc.com) vehemently insists that it should be turned off. But I've seen
a number of criticisms of Steve's "security expertise." Apparently, the FBI
used to receommend turning uPNP off but no longer does so.

Is there a consensus here?

Thanks Carey.

Lew,

That was my source for turning it off. I did see where the FBI recommended
turning it off but then they flip-flopped.

If the device require UPnP then they may need to be enabled. You will have
to read the documentation. I have both disabled on all my home computers
with no problems. --- Steve

When I disable SSDP Discovery Services and restart my system, the status
changes back to "Started". How can I prevent this from happening?

If you do not have a network, you do not need it running, disable it.

Steve Gibson is no more than a Scare Monger and is NOT a source for security information.
Disregard information at the GRC web site and *only* get security information from
authorative security sites !

For Example; US CERT, CIAC and Secunia.

What does the startup type show? It needs to be disabled and not just
stopped. If you leave it automatic it will start again after a system
reboot. Make sure you hit "apply" after changing it to disabled. --- Steve

You probably do not need it even if you are on a network. --- Steve

Not true. There are many software applications and hardware appliances that use uPnP to
setup a uPnP compliant NAT device to properly open and/or forward needed TCP and/or UDP
ports for proper communication.

Steven,

The startup type shows manual for UPnP and SSDP Discovery Services. I do
not see how to disable it, I just see how to start and stop the service. Can
you tell me how to disable? XP Pro SP2.

 

[Steven L Umbach]

And you can often work around such without using UPnP and all the noise it
creates on the network. --- Steve

 

[Guest]

David,

I thought I was disabling the service but in actuality I was only stopping
the service. I do not see an option on how to disable the service, can you
explain how to disable .

 

[Steven L Umbach]

There should be an option to set it to disabled in the drop down box for
startup type. You should see three options - automatic, manual, and
disabled. --- Steve

 

[Guest]

OK, I see it now. I right clicked the service and selected properties and I
now see the option to disable. Thnx for your help.
