If it is your own box and not a web hotel, then I will strongly
recommend using a regular database instead of the on demand
attach of a database feature.

Much fewer problems.

If it is your own box and not a web hotel

Did you really mean to say web "hotel" or was it supposed to be "host"? Just
wondering if "web hotel" is a term I'm not familiar with.

I mean to write "web hotel".

But a quick googling seems to indicate that the
term is only used in Denmark/Norway/Sweden. I
thought it was a common term. My apologies for
confusing people.

A web hotel in Denmark is a cheap web hosting
solution. You buy a standard package where you pay
a specific low amount per month, have a specific limit
on space used on the servers and a specific
software package. The servers are shared with
thousands of other users so performance is
non predictable. But it is cheap.

Compared with a professional web hosting
solution where you negotiate a customized
package.

The relevancy for the question is that the cheap
web hotel will either give you one database or may just
tell you to upload and attach the MDF while with
no choice while for the professional web
hosting you could ask for N databases to be
created.
