Issue/Introduction

When I use port 80 I get an app not found on the web browser. Uninstall reinstall and set the port to 8080 works like a champ.  Tried several times.

Environment

Release : 12.1

Component : CA OUTPUT MANAGEMENT WEB VIEWER FOR ALL PLATFORMS

Resolution

To see what is listening on port 80:

From the cmd prompt box, type

netstat -ano
Look for 0.0.0.0:80
Get PID number from right column

Bring up task manager (CTRL/ALT/DEL)
Click on the Services tab
Click on the PID column to sort, and you will see the name (if any) of the process listening on port 80.

How to determine if a port is reserved or blocked by company procedures - their help desk should know that

Used port 8080 because port 80 was not available.
