You can also verify that the systems is functioning as a VPN server by
obtaining a command prompt and issuing the command
netstat -a | find
"pptp". You should see a "LISTENING" line displayed indicating the
system is listening on the
Point-to-Point Tunneling Protocol (PPTP) connection.
C:\>netstat -a | find "pptp" TCP ANDY:pptp ANDY.example.lan:0 LISTENING
port 1723 is used for PPTP, which you can see if you use
netstat -a, so that numbers are displayed
rather than text descriptions for ports. If a VPN connection is active
at the time you issue the command, you will see the remote IP address
C:\>netstat -an | find "1723" TCP 0.0.0.0:1723 0.0.0.0:0 LISTENING TCP 192.168.0.8:1723 22.214.171.124:49359 ESTABLISHED UDP 0.0.0.0:21723 *:*
