During the installation of Microsoft SharePoint, the Central Administration Web site is established on a randomly-assigned TCP port by default. Allowing a randomly-assigned default may result in use of a port which violates DoD policy or conflicts with ports already in use. Use of certain well-known ports may also result in slow operational response or expose the application to known denial of service attacks.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.
