Hi,

I have an x-files problem on my XP. I run torrent lately and have no
downloading. So after quick research i've noticed, that there is port
forwarding problem:

http://www.utorrent.com/testport.php?port=39918

Checking port 39918 on xxx.xxx.xxx.xxx...

Error! Port 39918 does not appear to be open.

Pretty strange becouse i have not such a problem so far. I've disabled
my Kerio and still nothing. Win XP FW is disabled too. So I decided to
uninstall Kerio to see what happen and port is still closed.

Maybe my ISP configured sth on router, but when i connect other
computer to the same line, no problem occurs.

Anyone have any idea what can couse that problem???

Regards
Kordian

Maybe, malware or something is running on the machine, it has the port
and you don't know it.

No, no such other software is running on my pc.

And I have direct adsl connection to internet. As I said, other
computer connected to usb adsl modem has no such problems. :(

I try to uninstall latest hotfixes from windowsupdate and see what
happens

What are you talking about here?

How do you know something is not running that has that port in use on
that particular machine.

Have you even looked with tools like the NETSTAT command on the O/S,
Active Ports program (free) or TCPView program (free) to see what's
using the ports

Well, something got the port blocked, the PFW(s) may be blocking the
port or something is running and has the port in use and you don't know it.

Nothing, you're fishing for straws.
