Is there any way of using CMD to check if a port is open on a remote pc? Ive tried the ping command with ipaddress: portnumber but that doesnt work. Ive also check the technet on microsoft and have been unable to find anything that will give me a clue how to do this. Was just trying to trouble shoot a small issue with my hope pc from work, and see if a port at home was open or not, etc. Thanks for any help.
