ARDI and Port 80

ARDI and Port 80

Using IIS on an ARDI server may cause ARDI to be unavailable

Issue Description

ARDI runs on the normal HTTP (web) network port. If you're running other services - such as Microsofts IIS or some versions of Skype - on port 80, ARDI will not be available.

Explanation

Only a single program on a system is able to 'listen' on a port. While ARDI can be configured to listen on ports other than 80, this often provides a poor user experience and can cause issues with 3rd party plugins.

To use ARDI, you'll need to stop whatever program is using port 80 on your machine. 

Some examples of solutions appear below...

Resolution (IIS / World Wide Web Publishing Service)

1) Login to Windows on your ARDI server as an Administrator
2) Open Services
3) Find the World Wide Web Publishing Service in the list
4) Right-click the service, and choose Stop
5) To prevent this issue from happening in the future, open the properties of the service and change the start mode to Manual
4) Find the apache2 service, right-click and press 'start'

Because driver configuration information may have been unavailable, you might also need to restart the various ARDI services (such as drivers) as well. 

Resolution (Skype)

1) Close the Skype window
2) Find the Skype icon in your Notification Area, right-click and choose Close.
3) Open Services, find the apache2 service, right-click and press 'start'

Because driver configuration information may have been unavailable, you might also need to restart the various ARDI services (such as drivers) as well. 

Other

1) Open Powershell
2) Run the command...
  1. Get-Process -Id (Get-NetTCPConnection -LocalPort 80).OwningProcess
3) This should give you the name and/or process ID of the program using port 80.
4) Close that program, or stop its associated service
