Port ranges

[Guest]

I recently got a software firewall because certain ports were open on my
computer, I have plans to get a hardware one. doing a port scan I noticed
that a few of my ports were still open, 4 of them attually. And I was
wondering what ports were required by microsoft XP pro to run.

Thanks,
Jason

No open ports are required. It depends if you're on a network or if you
want to access the internet or not.

Pretty good primer...
How to read NETSTAT -AN results
http://www.geocities.com/merijn_bellekom/new/netstatan.html

To see what's listening, etc.
The o at the end of netstat -ano lists the PID #. You can match that up
with the PID # in Task Manager or with tasklist /svc to see what's doing
what.

Open a command prompt.
Start | Run | Type: cmd | OK |
Type: netstat -ano
Enter

For a list of all the switches and what they do...
Type: netstat /?
Enter
