Which Windows, netstat is builtin to some versions:
"Displays protocol statistics and current TCP/IP network connections.
NETSTAT [-a] [-e] [-n] [-o] [-s] [-p proto] [-r] [interval]
-a Displays all connections and listening ports.
-e Displays Ethernet statistics. This may be combined with
the -s
option.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each
connection.
-p proto Shows connections for the protocol specified by proto; proto
may be any of: TCP, UDP, TCPv6, or UDPv6. If used with
the -s
option to display per-protocol statistics, proto may be any
of:
IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
-r Displays the routing table.
-s Displays per-protocol statistics. By default, statistics
are
shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and
UDPv6;
the -p option may be used to specify a subset of the
default.
interval Redisplays selected statistics, pausing interval seconds
between each display. Press CTRL+C to stop redisplaying
statistics. If omitted, netstat will print the current
configuration information once."
I usually use netstat -o -a
