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.

Look, whatever port I pick, i have the same error Error! Port XYZ does not appear to be open.

I try on various ports, wide range of numbers and still has that error, doesnt matter if my PFW is running or not.

I run netstat -an, see what ports are open, do the test and..guess what :(

Strange, because if all ports are closed how can I use net, comunicator or emule (when I check the port with

UR right. Nothing happened.

I opened port TCP 33333 on the PFW running on this laptop connected on dial-up and then I set a rule on the port to allow all IP(s).

I ran the test on the port. It came back with port not open. Maybe you need to run some tests from some other port testing sites, to test the validity of the site above.

Are you sure the app running on both computers is configured similarly. The app needs to listen on the port for anything to happen.

Check with something like TCPview or CurrPorts.

BTW, when connecting your computer directly with the FW turned off make sure your network services are disabled.

I just checked an open port with the above link. It correctly reported "OK! Port x is open and accepting connections." So the site test seems to work.

Yep

What do you mean by saying "make sure your network services are disabled."

And here my CurrPorts

Well, I did pass that test the port was open. It was on port 80 HTTP as I do have the IIS Webserver running and listening on that port. After I stopped IIS, the test came back the port was closed.

What is meant by the disable the networking services is uncheck Client for MS networks and MS File and Print Sharing on the NIC with a direct connection to the modem with the PFW down so another machine on the Internet cannot network with it on the Windows Networking Ports. That's

Pretty strange, after i reinstaled hotfixes from february and my vpn client, everything went back to normal. So what was the problem?

Thanks for help. I really appreciate it!
