All of a sudden, this appeared in my network connections

[Doomer]

Intertnet Connection Internrt Gateway connected Internet Connection


Properties has one tab, a general tab. On it it says "allows you to connect to the internet through a shared connection on another computer.

It has a settings button that brings up another window that says "list the serves on your network that other users can access."

MSMSGS (192.168.1.124:10950) 4843 UDP
MSMSGS (192.168.1.124:11281) 60669 TCP

If I disable this connection, I loose my internet

I connect via cable and a Linksys router. Not through another computer.

I have 2 other computers. I disconnected them from the network and brought them up and they do not have this network connection.

Anyone know what's going on here?

hmmm
msmsgs is windows messenger, but can also be a virus
i assume the latter
do a full scan at
housecall.antivirus.com

 

[Doomer]

Both MSM and Windows messenger are uninstalled. Also msmsgs.exe does not exist on any of my machines.

 

[petey117]

have you run a virusscan

 

[Doomer]

You name it, I have run it.

 

[petey117]

oooh, i just reread your first post....
do you have more than 1 network connection? it seems that you have ICS enabled, and your machine is giving out IP addresses, which is why your other computers cannot connect
how many connections do you see in your network connections?

 

[Doomer]

ICS isn't even installed. There are two connections one is the normal Local network and the other is the one in my first post.

I have searched for some clue till I'm blue in the face. I wonder if this is something new?

 

[petey117]

right click on you local network, and see if it is "bridged"

 

[Doomer]

Nope, It's not bridged.

This is so frustrating. i can't find a clue as to what the heck this is.

 

[Doomer]

Just discovered that when I disable this connection, it disconnects my router from the web. When I enable it, the router reconnects.

 

[JackMDS]

It has to do with UPnP.

:sun:

 

[Doomer]

I used XP antispy to disable UPNP when I built them and just checked, it's still disabled.

 

[petey117]

run the networking wizard, and maybe it will fix it

 

[Doomer]

OK, In Add/Remove programs - Windows components - Networking Services is a service named

"Internet Gatway Device Discovery and Control client"

I unchecked it and the network conection disappeared and I still have Internet.

I checked a couple of my friends computers and they were set up the same exact way i.e. the above service was checked, and they did not have the network connection in question so I still don't know what's going on here. Nothing I did caused this, no new programs, no changes to the network config.

So I'm still in the dark.

 

[petey117]

as jackmds stated that is a uPNP service
it interacts with your router, and changes dynamically based on services or programs that you use.
i would not be concerned with it

 

[Doomer]

Thanks all,
After beating my head against the wall all freakin' day, I've come to the conclusion that it's harmless. Yes, I am paranoid and anything that makes me suspicious puts me into a search and destroy mode.

OK, I just opened network connections on one of my machines to try and help you and I found I have the exact same thing! I have an 'internet connection' and also a few services in the 'allowed' list which do not appear to correspond to the 'exceptions' in the windows firewall. A long time ago I had ICS enabled on another machine, but I got a router pretty soon after that, and I'm pretty sure I've reinstalled windows since then. This is weird.

The 'internet connection' is not present on any other machine. It does seem to be nescesary to have it enabled on the machine where it is present in order to access the internet, but not the local net. This baffles me completely. My router runs NAT, I can access the router via it's webserver and I can ping it regardless of whether the 'internet connection' is enabled or not, yet I am not able to access external sites with it disabled. The PC must be deliberatley blocking packets with non-local sources or maybe setting TTL to 1 so I can't route out...

I'm getting out the packet sniffers.

I have an established TCP connection to my router on 5431 on the machine the 'internet connection' is present on. I believe this is the service you are talking about, but did it cause this 'internet connection' to appear? And how did it get there in the first place? I never put the CD that came with the router into the PC... I never even used it with the original firmware...

I've been running Ethereal ever since this started and saw nothing that lookes suspicious (I did tons of ip lookups). Try going into Windos setup and uninstall it. I did, and now my internet works without it. My big question is, what caused it to suddenly appear out of the blue.

The "Internet Gateway" icon tells you that XP is seeing your Universal Plug and Play router. In order to see it:
1) UPnP must be enabled on the Router
2) Windows Firewall must have exceptions for the UPnP Framework ports (TCP 2869 and UDP 1900).

If either of these conditions aren't met, you won't get the "Internet Gateway" icon.

If the "Internet Gateway" icon is available, you will find that ports in the router will be automatically opened for services that you require, such as file sharing, chats, and other software that knows how to configure a UPnP router.

Thanks Rebate. Where the heck were you when all this started? lol
