Command-line view of ports in use
Here is a quick and easy way to dig into what ports are being used, and what apps are using them.
Step 1: Find out what ports are being used:
C:\>NetStat -o
Which will return the following (your list will probably be much longer):
Proto Local Address Foreign Address State PID
TCP EC968728:1108 somesite.corp.com:https ESTABLISHED 4072
Step 2: See what app (& more) is using that port:
C:\>TaskList /FI "PID eq 4072" /FO LIST /V
Which will return the following
Image Name: OUTLOOK.EXE
PID: 4072
Session Name: Console
Session#: 0
Mem Usage: 105,320 K
Status: Running
User Name: ****DomainName****\bgroth
CPU Time: 0:01:44
Window Title: Inbox - Microsoft Outlook
There you have it!
I used the following pages to dig into the NetStat and TaskList commands:
