checking ports

[simon]

could some one please tell me the easiest way to check
what ports I have set up for what, I have been told that
it is possible to disable a port as to reduce the
potential of being hacked.
I have receently installed a sygate firewall.

try this....

What ports are open on my PC?
The Netstat command can list currently used ports, which might be helpful if
you suspect an application is clashing with another one on an active port.
Use the -an switch to show all connections and listening ports in numeric
form.

C:\> netstat -an

KM is correct about netstat because it's built in (and always
there on NT+ with IP loaded.)

I like FPort from FoundStone.Com -- it's free and gives you
FILE PATHS to the process' exe location.

Consider a firewall -- Agnitum Outpost Firewall FREE version
or the purchase version is quite affordable.

You can also "stealth" your ports using IPSec filters (built-in
to Win2000+).

To check your open ports from OUTSIDE go to
