    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.

    You could use a portscanner or you could use a website based scanner like pcflank. Being at work though I would make sure nobody is gonna get upset your port scanning comps from your network :p

    *Edit* - ok I forgot pcflank uses the machine's ip that your on ... I have seen other web based port scanners that allow you to enter an ip (though the majority don't as it could be used for evil).

    you can open a command prompt and type netstat -a to see all connections to your pc...
    or try cmd prompt type telnet <ip address> <port number> and see if it answers

    yes but a netstat on your machine doesn't always tell you what others see from the outside ... it doesn't take into account routers/firewalls and the like.
