Site Administrator web application port is 3141. Here are instructions how to change it to 80:

  • The port is configured via httpd.conf file in the Site Administrator for SharePoint\SharePoint Information Portal\Python25\conf folder
  • I would recommend to back up this file before changing it
  • Open the file and replace the 3141 strings(5 occurrence) with 80
  • Restart the Quest.InfoPortal.WebAccess service
  • If the service is not started this means that 80 port is not free and cannot be used by Site Admin

That’s it
