I did the search as you suggested via this page, and do see the document to which you referred is in fact on the list. It should not be turning up on the web search results. I will be forwarding this information to our KB team for investigation.
Another document that initially returned with "The URL you've tried isn't returning content.", http://www.symantec.com/docs/TECH105816 (Title: "Symantec Endpoint Protection Client and Manager Version List") is a public-facing document, and does now display. This is not as detailed as the information given in the Release Notes document linked below.
In digging into the internal document's notes, I see that the XLS file was compiled from data from these three documents:
- http://www.symantec.com/docs/TECH103087 - Release notes for Endpoint Protection and Network Access Control 11
- http://www.symantec.com/docs/TECH101820 - Release notes for Symantec Client Security 3.1.x and Symantec AntiVirus 10.1.x
- http://www.symantec.com/docs/TECH102297 - Release notes for Symantec AntiVirus 10.2 Client for Vista and Windows Server 2008
Frankly, the information in these documents will be more dynamic than an Excel spreadsheet.
I can't find any reference to an Excel document with this information that was public facing, so if you have information as to where you had gotten that document in the first place (i.e., a KB article number, a URL) I'll be happy to follow up on it.
I hope this helps clarify things.
