particular error or issue that you might encounter when using an IronPort 
product. For example, a problem-and-solution article might explain what to 
do if a specific error message is displayed when you upgrade to a new version 
of the product.

Reference. Reference articles typically provide lists of information, such as 
the error codes associated with a particular piece of hardware.

resolve common issues related to IronPort products. For example, a 
troubleshooting article might provide steps to follow if you are having 
problems with DNS.

Each article in the Knowledge Base has a unique answer ID number.
