Why are all of my ports closed?

By bizzurks ·
I am running Windows XP Pro and I cannot find an open port. I disabled my firewalls and disconnected my router, so I have my PC directly connected to my modem. I even installed a fresh version of XP home, and still had the same problem. I finally called my ISP and they are not blocking me. I have searched every help forum and site I could find and apparently no one has ever had this problem.
Anyone have any ideas?

It isn't a port?

Is your network called installed?

Installed

by bizzurks In reply to It isn't a port?

No It's not and I kind of don't understand your meaning. I have never had this problem until a month or so ago. One instant I can access my ports and create working exceptions in my firewall and router. The next I can't find an open port none. Except four that are in use, but since I am accessing the internet I hoped most would assume those are working. I am pretty much I my wits end. Thank you for trying to help by the way.

uh, I meant network card

by Absolutely In reply to Installed

I guess I started typing 'installed' before
I finished 'card,' sorry. I meant to ask
whether you have a problem with the NIC
drivers because from the few details in your
original question it looked like you might
be a total n00b with a red exclamation point
next to your NIC in Device Manager. I guess
not. Good luck.

Most things that break with my PC I can research and problem solve. I built it i should be able to, at least. Still I know there are a lot of people out there that know more.. a lot more. I appreciate your help, sorry my original post was so vague.

PS You are probably on the right track and it is probably a very basic mistake I made.

If all of your ports are closed...

how is it you are accessing the Internet? You have to have an open port to do that.

Why would you want all of your 65000+ ports open? That is 65000+ avenues into your PC. Pay a visit to the site below and get a free port scan. And read the information Mr. Gibson has on the site. Open ports are not good. Closed ports are better, and stealthed ports are better yet.

I knew someone would point this out

by bizzurks In reply to If all of your ports are ...

Ok I do have four open ports 135, 139, 445, and 2869 but since their all in use I felt I did not need to mention them. The rest how ever are close. You are also right I do not want 65000+ port open just one or two, but I should be able to open them all if I wanted to, I can't. This is why I ask for help. I realize that the assumption is I am a slack jawed idiot, and though that may be true, I do know about basic interweb security. Thank you for recommending the site it is engrossing.

Something or you must have closed them!

Otherwise you should be able to get onto the internet!

How do you know these ports are open and the others closed?

Are you sure you didn't stop traffic via you modem?

Reset the modem and try again or disable the firewall that is closing these ports!

Already Reset It

by bizzurks In reply to Something or you must hav ...

My modem already been reset several times. I knew they are closed because my P2P program suddenly dropped it's speed. So via its help menu I ended up at a connection test site. The port the P2P program was operating on was closed. I went back and changed the port it operates on four times they were all closed. That's when I downloaded a port scanner, so I could check more than one port at a time. Turns out out of 65000+ ports I only have 135, 139, 445, and 2869 open. That's when I started looking for help. Thank you by the way for helping.

Hang on

"I knew they are closed because my P2P program suddenly dropped it's speed."

If the ports were closed the connection would stop, not a speed drop!

"That's when I downloaded a port scanner"

Hope you did this on another computer!

"I am running Windows XP Pro and I cannot find an open port. I disabled my firewalls and disconnected my router, so I have my PC directly connected to my modem. I even installed a fresh version of XP home"

If you did this all ports would not be closed, if you didn't install a SP2 version or did an install of SP2 then the firwall wouldn't be on. How did you activate the OS, if all ports were closed, did you ring?

Err.. Hmm

by bizzurks In reply to Hang on

You are right ports 135, 139, 445, and 2869 were open. I can't really use then for anything though. My new install was XP Home SP2 and you have 30 days to activate before you get shut out. The port scanner was installed on the same PC, it found the four open ports I had. Is that a conflict? Also P2P will work off of your internet connection but needs a port open for incomming request, otherwise you get preferenced out and it takes an hour to download 2 MB File. At least that is what I thought, if I am wrong let me know.
