How to change the default TCP port for Web Portal

Summary: Cayosoft Administrator is using IIS Server as the application server, and the Web Config tool installs and configures all required features including the IIS role.

After installing IIS on any Windows machine, by default IIS listens on port 80. Most of the time, it works fine. However, in some cases, you need to modify default IIS settings. One of the scenarios where you might need to change the port is if you already have another application server that is already configured to listen to port 80. In this article, we will explain how to change the default listening port of IIS from 80 to any other port of your choice.

Applies to: Cayosoft Administrator 5.X or later.

Ensure selected port availability

To ensure that the selected port is not already licensing by any application, you can run the netstat tool:

Start Command Line as administrator.
Insert there the string (replace <your_port> by the port number)
Copy
```
netstat -aon |find /i "listening" |find "<your_port>"
```
Here it is an example of how the output should look like: the port "80" is already listening, and "81" is available, so we can use it:

Change IIS settings

Open IIS Manager.
Navigate to Sites > Default Web Site.
Click the Bindings item on the right pane to open a dialog box.
In opened Site Bindings dialog, select http record from the table and click Edit....
Enter the new port number in the Port edit box and click OK.
Click Close on the Site Bindings dialog.
Select your server node on the left tree and click Restart Server on the right pane to restart IIS server.
Now the Web Portal is available on the new port, to check this type http://<server_name>:<new_port>/CayosoftWebAdmin in any browser.
