    Agent Handler can't install (Port 80 in use)

      Hi all, I am attempting to remotely install Agent Handler on a offsite server. But during installation, I was prompted that my Port 80 is in use by another program.


      But I couldn't figure out which program is using Port 80... Pls help.

      I ran this command: netstat -ano | findstr "80"

          Does the above help?

          • 2. Re: Agent Handler can't install (Port 80 in use)

            Hi all, I used NetStat -n and found this


            C:\>netstat -n

            Active Connections

              Proto  Local Address          Foreign Address        State
              TCP      ESTABLISHED



            It seems my server's Port 80 is connected to one of my user's system. How is that possible?


            Is he using some sort of Skpe that uses port 80? But why is it using my server's port 80 instead of my user's workstation own port?


            Most important question - How do I kill the process..? Heh heh heh...

              You've almost certainly got some sort of web server listening on this machine... IIS is the usual culprit   If you do a nestat -abo  you should see the executable that's listening on 80.


              HTH -
