Windows Network Out

J

Is there anyway to turn this off?

My Avast firewall is blocking what it calls Windows Network Out. It's
blocking it three or four times a second. The blocking doesn't cause
any problems, but it just fills up my firewall log, and I would like to
stop it from getting to the firewall.

I have turned off everything in Network and Sharing in Control Panel,
and that didn't do it.

It could be Windows Cloud.
What is the ip?

You could always unblock it.

Which port number is it?

Remote Port 137 and 138
Remote Address 192.168.1.255
Local Port 137 and 138
Protocol UDP

I don't know why it's called a remote address, it seems to be
originating from my computer.

I think I answered Paul's question also.

You are probably right. I could just allow the connection, and that
would remove it from the firewall logs.

I'm pretty sure it is just internal to my computer. I know the firewall
calls it Windows Network, but that IP address is associated with my
router, and I don't have a home network.

I'll keep trying, and if I can find a way I will disable it.

Read this, port 137 is the same. It's ok as your router will block it
from the net.

That's _probably_ your computer trying to see if there are other
computers on your network. Run a virus scan to make sure.

After reading Ken's post, I did some searching and found out that
NETBIOS is still enabled in Windows 7, and when I disabled it the
blocked IP address in the firewall went away, which eliminated about 90%
of the firewall log.

Here's where I found out how to disable it:

If you never use a second computer or file/printer sharing that's fine as
long as you remember what you disabled. Today many modems include a
router which is a great security measure. None of the new routers I use
have a real time logging, but you would not believe the amount of crap
blocked, when I did have real time logging.

I wonder if NETBIOS is still needed. If I do set up a home network, it
will be done through my router, which was supplied by AT&T, and the
router firewall doesn't accept a NETBIOS connection.

Another strange thing I noticed using Avast Network Connections, is that
even though Avast was blocking NETBIOS in the firewall, it was allowing
a Network connection to be established with Microsoft using NETBIOS.

I use DD-WRT firmware on my routers which has real time logging.

The router firewall is between the internet and the router and does not
affect anything on the lan. I don't know anything about Avast if it has a
built in firewall, but netbios should be allowed over the lan to find
other computers on the lan.
My guess is that Avast doesn't know you are on a lan, so it blocks
netbios to the "internet/lan". It's probably just a setting in the Avast
firewall.
The only way to test is to connect another computer to the router.
Never had to check my security suite rules, but never had a reason to see
how it handles netbios.

Maybe my security suite is smart enough to "see" I am on a lan ip address
and allows net bios without an alarm. Really don't know.

I just tried here, I disabled netbios on my notebook, I still had
access to the LAN.

But you may not 'see' another computer on the lan.

I was wrong. There is conflicting info after doing a search.
I only tried a third party firmware once and got too confused. LOL
