- Ports 135 & 445
- Posted by methanol on October 22nd, 2004
When I do a netstat -an these ports are always listening, I have a firewall
blocking all lower ports but I was wondering how I could close them all
together, or what programmes are using these ports?
Regards,
Chris B.

You can use a program called Active Ports to see what programs are using
what ports.. Search Google for "Active Ports". Should be available
from many sources...

Port 445 is the "messenger" service in NT, W2K and XP. It is not needed and is
pretty easy to disable without any ill effects. Port 135 is RPC/DCOM and is
harder to disable. Depending on what services you have running, you may not be
able to close it.
Gibson Research has a couple of free utilities to safely disable these services.

Or you can disable them yourself by changing the appropriate settings in
"Services."

I have a program (SafeXP) which "hardens" my win2k, and as
part of this it shuts down port 445. However, when I tried
to do a windows update I found that there was a problem with
network connectivity, so backtracking I re-enabled port 445,
and all went well. So, for some reason windows update needs
this port, which is fine, now I open/shut the port as I need.
No other program seems to complain about this.

I have port 445 closed and use Windows Update regularly. I closed my port by
disabling the "messenger" service, not with a utility. I suspect that "SafeXP"
does more than close the port.
