Thanks. Another trick I've learned is when seeing if a port is open on a remote target, telnet works very well. Yeah you have to install the feature first but it's very simple.

Great information Adam sir, it will be helpful if you can make a video on how to fix high CPU usage issue in Windows Server 2012 R2/2016 when running under Citrix environment and VMWARE EXSI environment, Server CPU usage always shows 100 percent despite being checked that there is no abnormal process usage by any of the process or programs

Question, if a port is not displayed but we know that it should be there for the system we are using, does that mean it's closed?

[@kcalderon03]

Two questions.
1. What does this mean (*:*) in the netstat -a results?
2. In the ITPro app, what is the course name?
Thanks!

How do you add a tcp port to listen?

a great tutorial, easy to understand.
can i find the open ports to anyone's system?
if yes, can i access their system with that open port?
if yes, how?

what if port not there?

[@juanjoseaguero6539]

If a port is open...how can I close that port ?

[@ITProTv]

Ports are opened by a service or program using them and maintaining the open state of the port to do so. If you want to close an open port, you must first identify the service or program that is using the port, then stop/remove/uninstall it to close the port. Hope this helps!
