Portal Site on WSS

I have two questions...

Could I create a complete portal for Internet with WSS 3.0 or MOSS is necessary for that?

I wanted to know if it is possible to install WSS 3.0 on Windows Server 2008 R2 开发者_如何学运维or Windows Server 2003 is the only possibility for this version of Sharepoint.

The answer to your first question really depends on your definition of portal and how broad it is. It is possible to have an efficient intranet solution with WSS without full blown SharePoint. Microsoft offers a lot of templates too, for specific site types.

To your second question, yes you can install WSS 3.0 on 2008 R2, but you will need to apply the latest service packs.
