We have an application team who has an web-based application configured to run on port 80. This application runs on JBoss. Due to someother dependency they had to install IIS on this server. However, their application was not listening to port 80 in JBoss. When checked port 80 was been used by the default website in IIS. We later unbinded the port 80 from IIS, fixed the issue.

1. Open IIS Manager
2. Select web site.
3. Click on “Bindings” under Action pane.
4. Click edit to change the port (we changed 80 as 8000)
5. Click OK to apply changes.

Thanks,
WintelAdmin
