How I can change the localhost HTTP Port?

I am trying xpages and I am getting a common error that is been reported here when I am testing locally.HTTP Server: Error - Unable to Bind port 80, port may be in use or user needs net_privaddr privilege

One of the suggestions is to change the port from 80 to something else, however I don’t see where or how I can change it.

Thanks for any suggestion on how to do it.

Subject: You can change the web preview port

In Domino Designer, choose the menu option File → Preferences, and go to the “Domino Designer” set of preferences. There is a “Web preview port” setting in the “General” section. If this is not set to port 80, you should adjust your URL from “http://localhost/whatever” to “http://localhost:8080/whatever” (for example, if your port setting is “8080”).

I have checked this in 8.5.3 designer

Subject: Thank … but what about in the client?

I really need is the setting for the client.

I don’t have the issue in the server, but I do not have a development server with the correct version, so I don’t want to test using production.

I think that is a setting in the local notes.ini but I cannot find which is the correct one.

Thanks again, waiting for your suggestion.

Subject: *No way to change that, you have to find what is using port 80 and shut that down…

Subject: To expand on that.

I’ve seen the issue before with AVG Anti-Virus (Web shield option interferes) and SkyPE.

If it is not any of them you can use the NETSTAT command

netstat -nab

and then look for what is on Port 80 local.

If you prefer a GUI then Process Monitor from Sysinternals is good.
