It's the same on our wiki too... except in Mediawiki:sitenotice. Try putting
{{NAMESPACE}} in Mediawiki:sitenotice (which is what the poster wanted), then viewing
pages in different namespaces, and you'll see what I mean. It's always
"MediaWiki".

Are you sure that {{NAMESPACE}} behaves this way? Both on my local
install and on
mediawiki.org, {{NAMESPACE}} is empty on pages that are
in the default namespace.
