• STS 1.0 – SharePoint Team Services
• SPS 2001 and 2003 – SharePoint Portal Server
• WSS 2.0 and 3.0 – Windows SharePoint Services (v3.0 is technically not a previous version of SharePoint as MOSS is based on the current WSS core functionality)
• MOSS 2007 – Microsoft Office SharePoint Server
• MOSS 2007/E – Microsoft Office SharePoint Server Enterprise Edition
• SharePoint 14 – next release due out later this year.
Because you are new to SharePoint, I will assume you will be working with the latest version, MOSS 2007. That is the version I am working with (and started on), and will be blogging about.Not all functionality you hear about is going to be available to you. Some vendors will only show you the Ferrari version when there is a Toyota version available as well. Yes you can have all the bells and whistles, but it comes at a cost. (This is Microsoft after all, lol).
You also need to know that even if you have a MOSS license, you will need Office 2007 (Word, Excel, PowerPoint) to leverage some of the functionality available in that release. The Toyota version is WSS and Office 2003, the Ferrari version is MOSS 2007 Enterprise Edition and Office 2007.
