SQL Express

Windows server 2003, IIS 6, Dreamweaver 8

Does anyone use SQL Express for their database on their production server?
Microsoft tells me I should not use Access any longer and they recommend I
use SQL Express. I tried to download .NET framework 2 on my windows 2000
pro machine, which is required for SQL Express and I could no longer get any
microsoft websites or google websites. Anyone else have problems installing
this?

Will my access databases import into the SQL Express database without a ton
of work? I don't see a forum for SQL Express, anyone have a clue where to
find one?

Thanks.
