ports open on windows 2000

By jhayesit ·
hi i have a pc(pc1) that i can't connect to remotely, like any shares etc. i used to be able to but not anymore. I can ping it and when i go to the machine i can map drives to other computers, but nobody can map to the pc1, even though there is shares. so i am wondering if there is a firewall installed, the user says she doesn't know, how can i see what ports are open on the pc?

thanks

ports open on windows 2000

Open up a Command Prompt and type in:

netstat -an


And you will get something like this (only a lot shorter)

ports open on windows 2000

I actually trimmed the above output. On my system I have many connections open since I am on a server.

Anyway, the things that are important to Windows File & Print Sharing (to be able to remotely connect to the machine you are having trouble with) will be TCP ports 139 and/or TCP port 445. These ports need to be in a LISTENING status.

If you do not have port 139 but 445 IS there, then you have NetBIOS over TCP/IP disabled, but File and Print Sharing is enabled. This is ok if you are in a Win2K/XP only environment. NT4 and the Win9x OSs used port 139; 2K & XP use either 139 or 445.

If NEITHER 139 or 445 are listed, then File and Print Sharing is disabled on this system. Just go to the properties for the network card on this troublesome system, and enable File and Print Sharing.

hope this helps
